Because of the word's meaning and the fact that neuter nouns are typically inanimate, neuter uses of the adjective are expected to be rare or absent (although metonymic use, as in Horace's caelibe vita, would be theoretically possible). No neuter nominative/accusative/vocative plural form is attested in the corpus of Classical Latin texts. Some New Latin grammars give the form as *caeliba[2], which is consistent with the consonant-stem inflection in the rest of the paradigm: note however that only a few positive adjectives have attested consonant-stem neuter plural forms in -a.
