A noun has
singular (единствено) and
plural (множествено) number (число). Unlike in English, where almost all nouns add -
s in the plural, in Bulgarian there are many endings and despite the rules listed below one cannot be absolutely sure which ending to use with which noun. Besides, when forming the plural some nouns alter additionally. That is why a noun should always be learnt together with its plural form. Generally if the noun ends in a vowel, it is removed before adding the plural suffix. Sometimes the stress changes position.
Count form Masculine
nouns which end in a
consonant have an additional, specialized plural. This form is called the count form or numerical form (бройна форма — broyna forma), and is used only after
cardinal numbers and the
adverbs
колко (how many),
толкова (this/that/so many),
няколко (several/a few/some):
пет / колко / толкова / няколко молива versus
тези моливи. An exception to this occurs in some
exclamations following
колко, when the ordinary plural is used and the inferred meaning is "what a large amount of!": e.g.
колко коня? (
kolko konya? "how many horses?" – numeric plural), but
колко коне! (
kolko kone! – ordinary plural, implying "look at all those horses!"). The count form is created with the endings -
а and -
я, and—unlike the usual plural—without any additional changes (no loss of the sounds -
ъ and -
е, no change of consonants, etc.), except for the moving of stress (it never falls on the last syllable, so if it is on the last syllable in the singular, it will move to the penultimate in the count form), and
metathesis of
ъ in the letter group
ръ. There are also a handful of
neuter nouns for parts of the body which also take a count form –
ramo (shoulder) → ramene / 2 ramena;
kolyano (knee) → kolene / 2 kolena.
* Some nouns have different count forms according to their meaning. When "литър" (litre) and "метър" (metre) mean measures of volume and length, their count form is "литра" and "метра" respectively. But when "метър" means "meter" (a device that measures and records the amount of electricity, gas, water, etc.) its count form is "метъра". The case is the same with "път": път ("road") – пътя and път ("time", "occasion", "instance") – пъти. The nouns "литър" and "метър" are the only ones that lose the "ъ" in their count forms.
** The usual plural form of the noun "ден" (day) is "дни" and its count form is "дена". "Дни" can be used instead of "дена", but not vice versa. The combinations of words
два дни and
два дена are both correct, but the sentence
Зимните дена са студени (Winter days are cold) is incorrect. The usual form must be used, not the count one –
Зимните дни са студени. The count form is avoided with nouns denoting persons and in such cases the usual plural form is much more preferred (
колко ученици – how many students,
осем ученици — eight students). The usual form is also used after masculine numbers (in Bulgarian some cardinal numbers have gender), ending in -
ма (these forms of the numbers are used only with male persons, not with other masculine nouns denoting inanimate objects) –
двама ученици (two students),
петима ученици (five students).
Irregular and variant forms Some nouns have irregular plural forms: • човек/čovek (person) — хора/hora (people) — души/duši (people — numerical form) • дете/dete (child) — деца/deca (children) Some neuter nouns have two or more plural forms (most of them with no difference in meaning). For example:
кълбо — кълба and кълбета, крило — крила and криле, рамо — рамена and рамене, коляно — колена and колене, море — морета and моря, дърво — дървета, дърва and дървеса, четене — четения and четенета. Some plural forms have different meanings:
дърва – fuel wood,
дървета – trees; some are used in specific contexts: the variants
моря (from
море),
поля (from
поле) are found only in poetry. In Bulgarian, there are some nouns that are only found in the singular, and they are uncountable. This category includes some abstract nouns (
материализъм – materialism,
сигурност – security, любов — love); some collective nouns (
студентство – students); and chemical elements and some other substances (
водород – hydrogen,
въглерод – carbon,
грис – semolina,
ориз – rice). There are also words which have only plural forms. These are nouns referring to objects composed of two identical parts (
очила – glasses,
ножици – scissors), and some concepts and objects consisting of many elements (
въглища – coal,
финанси – finances,
пари – money). ==Definiteness==
