Usage

Plural word for analysis The plural form of analysis is analyses, pronounced [ uh-nal-uh-seez ]. The plurals of several other singular words that end in -is are also formed in the same way, including hypothesis/hypotheses, crisis/crises, and axis/axes. A similar change is made when pluralizing appendix as appendices. Irregular plurals that are formed like analyses derive directly from their original pluralization in Latin and Greek. Do you know: What is the plural of thesis?

Use the noun analysis to refer to the way you understand something by looking at it in different ways and studying its different parts. Analysis is a noun that is used in many ways and by many fields. It makes sense, since it is "a method of studying the nature of something or of determining its essential features and their relations," which means everyone does it at some point. In fact, every time you solve a problem you use analysis. Analysis is also shorthand for psychoanalysis, used for understanding psychological and mental processes.
