Vowels Proto-Italic inherited all ten of the early post-
Proto-Indo-European simple vowels (i.e. at a time when laryngeals had colored and often lengthened adjacent vowels and then disappeared in many circumstances):
*i, *e, *a, *o, *u, *ī, *ē, *ā, *ō, *ū. It also inherited all of the post-PIE diphthongs except for
*eu, which became
*ou. Proto-Italic and
Old Latin had a
stress accent on the first syllable of a word, and this caused steady reduction and eventual deletion of many short vowels in non-initial syllables while affecting initial syllables much less. Long vowels were largely unaffected in general except in final syllables, where they had a tendency to shorten. Notes: Note: For the following examples, it helps to keep in mind the normal correspondences between PIE and certain other languages:
Monophthongs Initial syllables In initial syllables, Latin generally preserves all of the simple vowels of Proto-Italic (see above): • PIE "known" >
*gnōtos >
nōtus (
i-gnōtus "unknown"; Welsh "customary", Sanskrit
jñātá-; Greek
gnōtós)}) • PIE "alive" >

we- except before labial consonants or
velarized l [ɫ] (
l pinguis; i.e. an
l not followed by
i,
ī or
l): •
*welō >
volō "I want" (vs.
velim "I would want") •
*wemō >
vomō "I vomit" •
*westeros >
voster >
vester "your, of you (pl)" There are numerous examples where PIE appears to result in Latin
a instead of expected
o, mostly next to labial or labializing consonants. A group of cases showing
*-ow- >
*-aw- >
-av- (before stress),
*-ōw- >
*-āw- >
-āv- is known as '''Thurneysen–Havet's law''': examples include: • PIE >
*lawō >
lavō 'I wash' • PIE >
*oktāwos >
octāvus 'eighth' (but
octō 'eight') Other cases remain more disputed, such as: •
lacus 'lake', in contrast to Irish
a in open syllables when preceded by any of
*b,
*m;
*kʷ,
*w;
*l. Vine (2011) disputes the cases with
*moCV, but proposes inversely that
*mo- >
ma- when followed by
r plus a velar (
k or
g).
Medial syllables In non-initial syllables, there was more vowel reduction of short vowels. The most extreme case occurs with short vowels in medial syllables (i.e. short vowels in a syllable that is neither the first nor the last), where all five vowels usually merge into a single vowel: 1. They merge into
e before
r (sometimes original
o is unaffected) •
*en-armis >
inermis "unarmed" (vs.
arma "arms") •
*Falisiōi >
Faleriī "Falerii (major town of the
Faliscans)" (vs.
Faliscus "Faliscan") •
*-foro- "carrying" (cf. Greek
-phóros) >
-fero-, e.g.
furcifer "gallows bird" •
*kinis-es "ash" (gen.sg.) >
cineris (vs. nom.sg.
cinis) •
*kom-gesō >

*soceros >
socer, gen.
socerī 2. They become Old Latin
o >
u before
l pinguis, i.e., an
l not followed by
i, ī, or
l: •
*ad-alēskō "to grow up" >
adolēscō >
adulēscō (vs.
alō "I nourish") •
*en-saltō "to leap upon" >
īnsoltō (with lengthening before

Sikelós "a Sicilian" >
*Sikolos >
Siculus (vs.
Sicilia "Sicily") •
*te-tol-ai >
tetulī "I carried" (formerly
l pinguis here because of the original final
-ai) 3. But they remain
o before
l pinguis when immediately following a vowel: • Latin-Faliscan
*fili-olos >
filiolus "little son" • Similarly,
alveolus "trough" 4. Before /w/ the result is always
u, in which case the /w/ is not written: •
*dē nowōd "anew" >
dēnuō •
*eks-lawō "I wash away" >
ēluō •
*mon-i-wai "I warned" >
monuī •
*tris-diw-om "period of three days" >
trīduom >
trīduum 5. They become
i before one consonant other than
r or
l pinguis: •
*ad-tenējō >
attineō "to concern" (vs.
teneō "I hold") •
*kaput-es "head" (gen. sg.) >
capitis (vs. nom.sg.
caput) • Latin-Faliscan
*ke-kad-ai "I fell" >
cecidī (vs.
cadō "I fall") •
*kom-itājō "accompany" >
comitō •
*kom-regō >
corrigō "to set right, correct" (vs.

Sikelía "Sicily" >
Sicilia (vs.
Siculus "a Sicilian") •
*wre-fakjō "to remake" >
*refakiō >
reficiō (vs.
faciō "I do, make") 6. But they sometimes become
e before one consonant other than
r or
l pinguis, when immediately following a vowel: •
*sokiotāts "fellowship" >
societās •
*wariogājesi "to make diverse" >
variegāre • But:
*medio-diēs "midday" >
*meriodiēs (dissimilative rhotacism) >
*meriidiēs >
merīdiēs "noon; south" • But:
*tībia-kan- "flute-player" >
*tībiikan- >
tībīcen 7. Variation between
i and (often earlier)
u is common before a single labial consonant (
p, b, f, m), underlyingly the
sonus medius vowel: • From the root
*-kap- "grab, catch": •
occupō "seize" vs.
occipiō "begin" • From the related noun
*-kaps "catcher":
prīnceps "chief" (lit. "seizer of the first (position)"), gen.
prīncipis, vs.
auceps "bird catcher", gen.
aucupis •
*man-kapiom >
mancupium "purchase", later
mancipium •
*mag-is-emos >
maxumus "biggest", later
maximus; similarly
proxumus "nearest",
optumus "best" vs. later
proximus,
optimus •
*pot-s-omos >
possumus "we can";
*vel-omos >
volumus "we want"; but
*leg-omos >
legimus "we gather", and all other such verbs (
-umus is isolated in
sumus,
possumus and
volumus) •
*sub-rapuit >
surrupuit "filches", later
surripuit Medially before two consonants, when the first is not
r or
l pinguis, the vowels do not merge to the same degree: 1. Original
a,
e and
u merge into
e: •
*ad-tentos >
attentus "concerned" (cf.
tentus "held",
attineō "to concern") •
*sub-raptos "filched" >
surreptus (vs.
raptus "seized") • Greek
tálanton >
*talantom >
talentum •
*wre-faktos "remade" >
refectus (cf.
factus "made") •
*kom-dapn-ō >
condemnō "convict" (cf.
damnō "disapprove") 2. But original
i is unaffected: •
*wre-likʷtos "left (behind)" >
relictus 3. And original
o raises to
u: •
*ejontes "going" (gen. sg.) >
euntis •
*legontor "they gather" >
leguntur •
*rōbos-to- >
rōbustus "oaken" (cf.
rōbur "oak"
dexterus (cf. Greek
deksiterós) •
*magisemos >
maximus "biggest" (cf.
magis "more") •
*priismo-kapes >
prīncipis "prince" gen. sg. (nom. sg.
prīnceps repperī "I found" (cf.
peperī "I gave birth"
*agr̩s >
*agers >
*agerr >
ager •
*faklitāts >

*feret "he carries" >
fert •
*imbris "rainstorm" >
*imbers >
imber •
*tris "three times" >
*tr̩s >
*ters > Old Latin
terr >
ter Sometimes early syncope causes apparent violations of Exon's Law: •
kosolinos "of hazel" >
*kozolnos (not
**koslinos) >
*korolnos >
*korulnos (
o > u before
l pinguis, see above) >
colurnus (metathesis) Syncope of
-i- also occurred in
-ndis,
-ntis and
-rtis.
-nts then became
-ns with lengthening of the preceding vowel, while
-rts was simplified to
-rs without lengthening. •
*frondis "leaf" >
*fronts >
frōns •
*gentis "tribe" >
*gents >
gēns •
*montis "hill" >
*monts >
mōns •
*partis "part" >
*parts >
pars Final syllables In final syllables of polysyllabic words before a final consonant or cluster, short
a, e, i merge into either
e or
i depending on the following consonant, and short

legis, legit "you gather, he gathers") • Proto-Italic
*wrededas, *wrededat >

Final syllables Mostly like medial syllables: •

*-ai >
ī in multisyllabic words: Latin-Faliscan
peparai "I brought forth" >
peperī •
*-eu/ou- >

manūs Different from medial syllables: •
-ai >
ae in monosyllables: PIE "before" >

-ei >
ī (not
ū): PIE o-stem plural
*-oi >
-ī (cf. Greek
-oi); •
-oi >
ī also in monosyllables: PIE "who" >
quī.
Syllabic resonants and laryngeals The PIE syllabic resonants generally become
em, en, or, ol when between consonants, as in most languages (but
Greek e/a/o respectively, Sanskrit
i): • PIE "put" > L
factus, with /k/ of disputed etymology (cf. Greek
thetós, Sanskrit
hitá- L
pater (cf. Greek
patḗr, Sanskrit
pitṛ́, English
father) • PIE "given" > L
datus (cf. Greek
dotós, Sanskrit
ditá-) A sequence of syllabic resonant + laryngeal, when before a consonant, produced
mā, nā, rā, lā (as also in Celtic, cf. Greek
nē/nā/nō, rē/rā/rō, etc. depending on the laryngeal; Germanic
um, un, ur, ul; Sanskrit
ā, ā, īr/ūr, īr/ūr; Lithuanian
ím, ín, ír, íl): • PIE "born" >
gnātus "son",
nātus "born" (participle) (cf. Middle Welsh "relative", Greek
dió-gnētos "Zeus' offspring", Sanskrit
jātá-, English
kind,
kin) • PIE "grain" >
grānum (cf. Old Irish , English
corn, Lithuanian
žìrnis "pea",
jīrṇá- "old, worn out") • PIE "wool" >
*wlānā >
lāna (cf. Welsh , Gothic
wulla, Greek
lēnos, Lithuanian
vìlna, Sanskrit
ū́rṇa-)
Consonants Aspirates The Indo-European voiced aspirates
bʰ, dʰ, gʰ, gʷʰ, which were probably breathy voiced stops, first devoiced in initial position (
fortition), then fricatized in all positions, producing pairs of voiceless/voiced
fricatives in
Proto-Italic:
f ~
β, ''
~ ð'', '
~ ', '
~ ' respectively. The fricatives were voiceless in initial position. However, between vowels and other voiced sounds, there are indications—in particular, their evolution in Latin—that the sounds were actually
voiced. Likewise, Proto-Italic /s/ apparently had a voiced allophone [z] in the same position. In all Italic languages, the word-initial voiceless fricatives
f,
θ, and
χʷ all merged to
f, whereas
χ debuccalized to
h (except before a liquid where it became
g); thus, in Latin, the normal outcome of initial PIE is
f, f, h, f, respectively. Examples: • PIE "carry" >
ferō (cf. Old Irish "bears", English
bear, Sanskrit
bhárati) • PIE "brother" >
*bʰrā́tēr >

β,
ð,
ɣ,
ɣʷ. In Osco-Umbrian, the same type of merger occurred as that affecting voiceless fricatives, with
β,
ð, and
ɣʷ merging to
β. In Latin, this did not happen, and instead the fricatives defricatized, giving
b, d ~ b, g ~ h, g ~ v ~ gu. is the simplest case, consistently becoming
b. • PIE "beaver" > *

fingō (cf. Old Irish "erects, builds", Gothic
digan "to mold, shape") has three outcomes, becoming

S-rhotacism Indo-European
s between vowels was first voiced to [z] in late
Proto-Italic and became
r in Latin and
Umbrian, a change known as
rhotacism. Early Old Latin documents still have
s [z], and
Cicero once remarked that a certain Papirius Crassus officially changed his name from Papisius in 339 .., indicating the approximate time of this change. This produces many alternations in Latin declension: •
est "he is", fut.
erit "he will be" •
flōs "flower", gen.
flōris •
mūs "mouse", pl.
mūrēs Other examples: • Proto-Italic
*a(j)os,
a(j)esem >
*aes,
aezem >
aes,
aerem "bronze", but PI
*a(j)es-inos >
*aeznos >

*auzōs,
auzōzem >
aurōra "dawn" (change of suffix; cf. English
east,
Aeolic Greek aúōs, Sanskrit
uṣā́s) • Proto-Italic
*swesōr >
*swozōr >
soror "sister" (cf.
Old English sweostor, Sanskrit
svásar) However, before another
r,
dissimilation occurred with
sr [zr] becoming
br (likely via an intermediate
*ðr): • Proto-Italic
*keras-rom >
*kerazrom ~
*keraðrom >
cerebrum "skull, brain" (cf. Greek
kéras "horn") • Proto-Italic
*swesr-īnos >
*swezrīnos ~
*sweðrīnos >
sobrīnus "maternal cousin"
Elision In groups of stop + /s/ before unvoiced consonants, the stop was lost: • Proto-italic
*subs-teneō > latin
susteneō "hold up" Syncopated words like
dexter ( latin
īdem "same" Clusters involving /s/ were also lost before voiced consonants, also with compensatory lengthening: • Proto-italic
*eks-dowkō >
*es-dowkō > latin
ēdūcō "draw out"
Assimilation Sequences of
dl, ld, nl, ln, rl, ls, and
lw became
ll: • Proto-Italic
*sed-lā > Latin
sella "seat" • Proto-Italic
*saldō > Latin
sallō "Salt" • Proto-Italic
*korōnelā >
*korōnlā > Latin
corōlla "wreath" (diminutive of
corōnā "crown") • Proto-Italic
*kolnis > Latin
collis "hill" • Proto-Italic
*agrolos >
*agrlos >
*agerlos > Latin
agellus "little field" (diminutive of
ager "field") • Proto-Italic
*wel-esi >
*welsi > Latin
velle "to want" • Proto-Italic
*moldwi- >
*molwi- > Latin As shown by
agellus this assimilation occurred after syncopation. Original sequences of
rs (i.e not derived from other sources or from syncopation) became
rr: • Proto-Italic
*feresi >
*fersi > Latin
ferre "to carry" Sequences of
nr become
rr: • Proto-Italic
*in-regō > Latin
irrigō "direct water to a place" Sequences of labial stops and nasals become
mm and
mn respectively: • Proto-Italic
*supmos > Latin
summus "
highest, top" • Proto-Italic
*swepnos > Latin
somnus "
sleep"
Other /k/ became /g/ before /n/ (possibly later becoming [ŋn]); word initially this /g/ (no matter its source) was also often later dropped: • PIE > *
degnos >
dignus "worthy" • Early Latin
gnōscō >
nōscō "to understand" Final /d/ was lost after long vowels beginning in the late 3rd century BCE: • PIE masc. ablative singular >
-ōd >
-ō • PIE "me" >
mēd >
mē Initial (attested in Old Latin as
du-) becomes
b-, thus compensating for the dearth of words beginning with
*b in PIE: • PIE "injure" >
duellom "war" >
bellum (a variant
duellum survived in poetry as a trisyllabic word, whence English "duel") • PIE "twice" >
duis >
bis (cf. Greek
dís, Sanskrit
dvis) /n/ underwent
dissimilation to /r/ when followed by /m/. • PIE "offspring, seed" > Latin "seed" • PIE (from the root “to sing”) > Latin "song" ==See also==
