Pali is a highly inflected language, in which almost every word contains, besides the root conveying the basic meaning, one or more affixes (usually suffixes) which modify the meaning in some way. Nouns are inflected for gender, number, and case; verbal inflections convey information about person, number, tense and mood.
Nominal inflection Pali nouns inflect for three
grammatical genders (masculine, feminine, and neuter) and two numbers (singular and plural). The nouns also, in principle, display eight
cases:
nominative or
paccatta case,
vocative,
accusative or
upayoga case,
instrumental or ''
case, dative or sampadāna
case, ablative, genitive or sāmin
case, and locative or bhumma'' case. However, in many instances, two or more of these cases are identical in form; this is especially true of the genitive and dative cases, which are only optionally distinguished in the singular of the a-stems (the dative can express goal or time period). Some rarer declension patterns have an alternation between strong stems (nominative, vocative and accusative singular, nominative plural), weak stems (before endings beginning in a consonant) and middle stems (before ending beginning in a vowel). The accusative expresses, besides a direct object, also the direction of movement and the goal of an action, as well as an extension of time and space.
a-stems a-stems, whose uninflected stem ends in short
a (), are either masculine or neuter. The masculine and neuter forms differ only in the nominative, vocative, and accusative cases.
ā-stems Nouns ending in
-ā () are almost always feminine.
i-stems and u-stems Masculine and neuter i-stems and u-stems differ only in the nominative and accusative cases. The vocative has the same form as the nominative. Feminine i-stems and u-stems may have a short or long vowel in the nominative, but the rest of the endings are the same.
s-stems S-stems are neuter and decline only in the singular.
nt-stems Nt-stems are masculine and may take the same endings as a-stems (
-anto etc.), but their original declension has an alternation between a strong stem in
-ant and a weak stem in
-at, as follows:
an-stems An-stems are masculine or neuter. They may undergo consonant assimilations and alternate between a strong stem in
-ān, a weak stem in -
n or
-in and a middle stem in
-u. When the stem contains a double consonant, the weak stem has
-an or
-un and the middle has
-a.
in-stems In-stems are masculine. They, too, may be influenced by i-stems, but their characteristic declension has an alternation between a strong stem in
-in and a weak one in
-i. Possessive adjectives in
-ī like
balī "strong" (feminine
balinī, neuter
bali) decline in the same way.
ar-stems These include relational nouns (masculine and feminine) and agent nouns. Relational nouns have a short vowel in the strong stem, while agent nouns have a long vowel.
Degrees of comparison • Usually the comparative degree is formed with the suffix
-tara and the superlative with
-tama: e.g.
paṇḍita "wise" -
paṇḍitara "wiser"
- paṇḍitama "wisest". • In some cases the comparative is formed with
-iya and the superlative with
-iṭṭha:
pāpa "sinful" -
pāpiya -
pāpiṭṭha. • Another superlative suffix is
-(i)ma. • Certain adjectives exhibit
suppletion:
sant - seyya - seṭṭha "good",
yuva - kaniyya - kaniṭṭha "young",
vuḍḍha - jeyya - jeṭṭha "old".
Pronouns The
personal pronouns for the 1st and 2nd person are declined as follows: The demonstrative pronoun
so "that" doubles as a 3rd person pronoun. It is declined as follows: A variant with
n- instead of
t- also occurs: e.g.
naṁ instead of
taṁ. With the addition of the prefixed element
e- to the forms of
so, a proximal demonstrative "this" is formed:
eso, etc. There are two other demonstrative pronouns: proximal
ayaṁ "this" and
asu "that". They are declined as follows: The
relative pronoun is
yo. It is declined with the same endings as
so (see above). The
interrogative is
ko, which also takes the same endings, except that the neuter ("what") is
kiṁ. From it are derived
katara,
katama "which",
kati "how many" and
kittaka "how much". An
indefinite pronoun can be formed by adding the particle
-ci to the forms of the interrogative:
koci "someone" They also agree with the subject in
person (1st, 2nd and 3rd) and
number (singular and plural). The Old Indic
middle is preserved, but is rarely used, survives only in some forms and there is rarely a semantic distinction between it and the corresponding active, so it may be described simply as a type of conjugation. When it does express a meaning, it is an action done for the benefit of the subject.
Endings There are three sets of endings: • primary: used in the present and the future (and sometimes in the optative); • secondary: used in the preterite and the conditional (and sometimes in the optative); • imperative. The endings are as follows:
Conjugations All regular verb forms are constructed from the same (historically present) stem, but there are also frequent historical forms derived directly from the root. There are two productive conjugations: • 1st conjugation, with a stem in
-a (
labh-a-ti "to get"); • 2nd conjugation, with a stem in a long vowel, most often
e (
cint-e-ti "to think"), sometimes
ā (
suṇ-ā-ti "to hear"), rarely others (
kar-o-ti "to do"). Other patterns are mostly historical relics.
Present The present tense is formed by adding the primary endings to the present stem. Verbs with stems in
-e- change it to
-aya- in the middle.
Future The future is formed with the suffix
-(i)ssa- + the primary endings, although the
-ss- may be reduced to a single
-s- or further lenited to
-h-. Again, verbs in
-e- may or may not replace it with
-aya-. Vowels other than
-e- are dropped and replaced by
-i-; e.g.
suṇāti "to hear" -
suṇissati "he will hear". Some verbs may add
-ssa directly to the stem, causing various sandhi changes: e.g.
labhati has the alternative future form
lacchati (from
labh-ssa-ti).
Conditional The conditional is formed like the future, from the present stem and the future suffix
-(i)ssa-, but it differs from it by using the augment and secondary endings. In addition, the ending in the 3rd plural is -
ṁsu. Although forms for the middle are given by Pali grammarians, only the 3rd singular is actually attested. It expresses a condition or result that has not been or cannot be realised.
Optative The optative is formed either with the suffix
-eyyā- and the primary or secondary endings or with the suffix
-e- and the secondary endings. They are added to the present stem, but the final vowel of the stem is dropped, so there is no difference between the conjugations. Besides wishes, the optative may express a possible or unreal action in conditional constructions. Some exceptional verbs form the optative with
-yā- rather than
-e(yya)-, resulting in sandhi changes:
jānāti "to know"
- jān-
yā > jāñña. Imperative Only verbs of the 1st conjugation may use the bare stem as a 2nd singular imperative, while those of the second take
-hi. Verbs in
-e- may or may not replace it with
-aya-. In the 1st person, the indicative form may be used with the function of an imperative.
Preterite The preterite is formed by adding the secondary endings to a preterite stem, which is constructed as follows: • 1st conjugation – mostly with the suffix
-i(
s)
- (e.g.
labhati -
labhi * Note that the 1st and 2nd plural forms of e
-verbs usually belong to the -i
(s
)-
aorist. An example of consistent s
-aorist is seen e.g. in the preterite of karoti
: 3rd singular akāsi (
labbbhati "is obtained";
chindati "to cut" -
chid-ya-ti >
chijjati "is cut". The productive pattern with the vowel
-i/ī- before
-ya- is found, inter alia, with verb stems in
-e- (e.g.
cinteti -
cintiyati "is thought") and with verb stems in a heavy syllable:
chindati "to cut" -
chind-i-ya-ti "is cut". However, the synthetic passive is not often used; more commonly, various periphrastic constructions are used such as the copula plus the past participle (
samannāgto hoti "he is endowed") or verbs coupled with abstract nouns. A similar suffix
-(i/ī/ā)ya- is used to form productively denominative verbs from nouns and adjectives:
pihā "desire" >
pihāyati "to desire".
Causative Causative stems are formed by adding either one of two suffixes: •
-e- or
-aya-, more commonly to the root, e.g.
gam-e-ti "causes to go" (sometimes with
vrddhi:
kar-
oti 'does', but
kār-
eti 'causes to do') •
-pe- or
-paya-, normally to the present stem and to roots ending in
-Cā: jānā-pe-ti "make known, inform". Even double causatives occur, with the repetition of the causative suffix producing the shape -
pāpe-, as in
rūhati "grow" >
ropeti "to plant" >
ropāpeti "to cause to be planted".
Non-finite verb forms • The
infinitive takes the ending
–(i)tuṁ (rarely
-tuṁye,
-tave,
-tāye). It is productively added to the present stem, whose final vowel is dropped:
pucchati "ask" -
pucchituṁ. There are also older infinitives with the ending added directly to the root, often resulting in sandhi: e.g.
puṭṭhuṁ to the same verb. • The
present participle is formed with the suffix
-nt(a)- added always to the present stem in the active voice; it is declined like nt-stems (thus, with the suffix alternating between
-ant- and
-at-). In addition, the suffix may be reduced to
-ṁ word-finally (
labhaṁ or
labhanto "obtaining"
, cintento "thinking"). In the feminine, the ending in the nominative is
-antī (
labhantī) and the rest is declined mostly like a feminine i-stem. In the middle, the ending is
-māna- (rarely
-āna-):
labhamāno. • The
participle of need is formed by adding one of the suffixes
-(i)tabba,
-anīya/aniya/aneyya, or, rarely,
-tāya/tayya/teyya or
-(i)ya-: e.g.
pucchitabba "which can/should be asked" and
kātabba,
karanīya, kāriya, kayya (
desita
"(which is) preached". However, very many verbs add the suffix -ta
or -na
to a stem that is irregular and unpredictable (originally the Old Indic weak grade of the root: e.g. suṇāti -
suta
"heard", pucchati
- puṭṭha
"asked"). The endings often undergo assimilation and other sound changes due to the preceding consonant: e.g. labbhati
> laddha
"obtained", yajati
"to sacrifice" - iṭṭha, bhaj-na > bhagga'' "broken". Its meaning is usually passive in transitive verbs and active in intransitive verbs, but an active meaning is occasionally found with transitive verbs as well. • Occasionally, a
past active participle is derived from the past participle by adding the suffixes
-vant- or
-āvi(n)- :
e.g. bhuttavanta "one who has eaten". • The
gerund/absolutive, which always has anterior meaning, is formed most commonly with
-(i)tvā: productively to the present stem as in
cintayitvā,
cintetvā "having thought", but sometimes added to the root in older forms, which may result in sandhi:
labh-
tvā > laddhā "having obtained". It is also formed with
-(t-)(i)yā, especially with prefixed/compound verbs (
ā-gam-ya > āgamma "having come back"), and occasionally with
-tvāna,
-tūna,
-yāna and
-aṁ.
Syntax The verb is usually clause-final, but that is not obligatory. Pure/original
adpositions (preposed or postposed) are rare, but adverbs, declined nouns and gerunds may be used adpositionally. Some frequent conjunctions such as
ca ('and'),
va ('or') are added enclitically to the phrases they join or to the first words of the clauses they join. The conditional particle
ce ('if') is also enclitic. A quotative enclitic particle is
ti. However, there are also clause-initial conjunctions such as
sace ('if') and conjunctions placed between the conjuncts such as
udāhu ('or'). There are many other enclitics, e.g. the emphatic
kho ('precisely') and
pi ('also', 'but'). A combination of a noun with a participle, when both are inflected in the locative, and, less commonly, genitive or accusative, can function as an
absolute construction expressing "after", "when", "if" etc. The copula may be omitted. Prohibition is expressed by the particle
mā followed by the preterite indicative (more rarely optative or imperative). In contrast to Sanskrit, external
sandhi (i.e. sandhi between words) is usually not applied in Pali and is always optional. The common use of sandhi is restricted to function words such as adverbs, prepositions, pronouns, numerals and the copula verb, which may be pronounced as
clitics and then undergo sandhi with the words they are adjoined to., such as combinations of verb and object, adjective and noun, and adverb and verb Compound or prefixed verbs are often formed with (historical) adpositions and adverbs as first compound members. Suffixation is also widespread. Some notable suffixes are listed below: • Action nouns are formed: • from verbs:
-na,
-a,
-nā,
-taṁ,
-tā,
-tti,
-tta; • Abstract nouns are formed: • from adjectives:
-ya; • from nouns and adjectives:
-tta,
-tā The suffixes
-ā and
-i may also form abstract nouns. • Agent nouns are formed with
-ū,
-(a)ka,
-tar,
-in and
-vin. •
-(a)ka is also a
diminutive suffix. •
-tima forms ordinal numerals. Adverbs can be formed with suffixes such as: • -
tra, -
ttha : place (
atra, ittha "here",
tatra "there") • -
dā : time (
tadā "then") •
-thā, -thaṁ : manner (
tathā "thus",
itthaṁ "in this way") •
-hiṁ : direction, "to" (
tahiṁ "there, thither, in that direction") •
-to : "from" (
ito "from here, hence") ==Linguistic analysis of a Pali text==
