Masculine plural: -и, and the -ов-/-ев- infix
Most masculine nouns simply add -и to the consonant-final singular: студент → студенти, пријатељ (friend) → пријатељи. Nothing else changes.
A monosyllabic masculine noun - one syllable in the nominative singular - inserts -ов- or -ев- before that same -и. After a hard final consonant the infix is -ов-: град (city) → градови, мост (bridge) → мостови. After a soft/palatal final consonant (ч, ж, ш, ђ, ћ, џ, љ, њ, ј, ц) the infix is -ев- instead: кључ (key) → кључеви, нож (knife) → ножеви.
Feminine and neuter plural
Feminine nouns ending in -а swap it for -е: жена (woman) → жене, књига (book) → књиге. Feminine nouns ending in a consonant instead - the exception class from noun-gender-a1, like ноћ - take -и: ноћ (night) → ноћи.
Neuter nouns swap their singular -о or -е for -а: село (village) → села, поље (field) → поља. This covers most neuter nouns cleanly, but a small class of nouns ending in -е inserts an -ен- infix instead of a plain swap - име (name) → имена, време (time) → времена - so it isn't quite as exception-free as it looks.
