Frequently asked questions
What is the plural of “analysis”?
The plural is “analyses”. Many words from Latin and Greek keep their original plural endings.
How do I make a compound noun plural?
Usually pluralise the last word (school bus, school buses). For “mother-in-law” the main word changes: “mothers-in-law”.
Why are some plurals irregular?
They come from older forms of English or from other languages, so they do not follow the regular -s rule.
