Most plural nouns in English end in ‘-s’ or ‘-es’. Nouns that end in s/es are regular and simple to form: all you have to do is add ‘s’ or ‘es’! We see this with most nouns: ‘dog’ plural is ‘dogs’, cat turns to cats, book is books, ‘table’/ ‘tables’, and so forth. Plural nouns ending in anything other than ‘s’ or ‘es’ are irregular.

Greek pluralization rules

Despite Greek nouns ending with ‘-es’ as plurals, they are still irregular, since, instead of adding ‘-es’ to the word’s ending, the ‘-es’ is swapped with ‘-is’ from its singular case. Because ‘-esreplaces the suffix of its singular noun form (the -is), this changes how we spell and pronounce ‘analyses’ as a plural and other Greek words.

Analysis/analyses share singular/plural noun patterns with many Greek words: diagnosis, crisis, synopsis, oasis, synthesis, thesis, and nemesis all end in -sis as singular nouns. Each similarly mimics the same plural form; i.e., substitutes the -sis with -ses: diagnoses, crises, oases, syntheses, the Greek nouns list goes on).

Apart from being irregular plural nouns, these words have another thing in common: they’re all Greek. Greek occupies roughly 5% of the English language. Most English words come from the Germanic languages, which include Dutch, German, Old Norse, Old Frisian, and a few others.

💡Study Tip

For the plural of analysis, change the -sis ending to -ses: analyses.
