This template provides the inflection of Bulgarian feminine nouns that end in a consonant + я, which means that they form the vocative with -ьо (зeмя - земьо, неволя - невольо, etc.). The parameter is the singular indefinite form without the final -я (зем and невол respectively). For example, {{bg-noun-f-ya2|зем}} produces the inflection of the noun земя.

The template adds the entry to Category:Bulgarian nouns.
