"Analysis" singular in sentence examples.

Analysis is an irregular plural noun form in English—which is likely the reason why it’s often confused in writing. Analysis plural is analyses, and this is peculiar for us English language speakers and learners to comprehend.

Most plural nouns in English end in -s or -es. Nouns that end with an –s/-es are regular nouns, and they’re simple to form: just add the s! For example, dog plural is dogs, cat/cats, book/books and table/tables. All other plural noun endings are irregular.

Words that end in -sis

The thing about the word analysis is that it does end in plural; –es, i.e., analyses. Why then, is analyses considered irregular when it adheres to the norm and uses the -es as a plural noun? Most nouns one attaches an -s or -es to convert the noun to from singular to its plural form. Analyses works different: the -es suffix is not simply added or glued to the tail end of the word; rather, the -es replaces the suffix of its singular noun form (the -is,) and so effectively changes the spelling (and pronunciation) of the word.

Still, analysis/analyses are not alone: 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, theses, nemeses, . (bases, hypotheses, paralyses, axes the Greek nouns go on).

Greek nouns in English

Apart from being irregular plural nouns, these words all 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 includes Dutch; German, Old Norse; Old Frisian, and a few others.

Words like diagnoses, crisis, analysis and the like have all conserved their original Greek form in both the singular and plural  forms. That’s pretty incredible, and means these words have endured through time since the Ancient Greece—and that we can all speak a little Greek!
