-a¹

(Received Pronunciation) IPA: /ɑ/, /ə/

(General American) IPA: /ɑ/, /ə/

Suffix

plural of -um
plural of -on

Etymology

From the homographic case endings of the nominative, accusative, and vocative forms of numerous Latin neuter second declension nouns.

Usage notes

Whereas the regular pluralization in English involves adding -s or -es, English words derived from a Latin/Greek where the Latin/Greek would pluralize from -on (Greek) or -um (Latin) to -a do not always do so. Usage of -a instead of -s differs between words: sometimes the two are interchangeable (e.g. memorandums/memoranda, polyhedrons/polyhedra), sometimes one is far more common than the other (e.g. neurons over neura, automata over automatons), and sometimes one is completely absent from usage (e.g. bacteria over bacteriums, dendrons over dendra)
