– Phenomena is the plural of phenomenon, so lemma must be the plural of lemon, right?

– Ah, since lemma’s plural is lemmata, lemmata must be the grand plural of lemon.

– So one lemon, two lemma, and three lemmata.

– I’m not sure if it shouldn’t be “one lemon, two lemma, and four lemmata” because lemmata should square the lemma.
