The Origin of Analysis or Analyses

The word “analysis” comes from the Greek word “analusis,” meaning a breaking up or a thorough examination. Over time, English adopted the word to mean the detailed study of data, information, or ideas.

The plural form, “analyses,” follows standard English rules for words ending in “-is” (Greek origin), where the “-is” changes to “-es” in plural:

• Crisis → Crises
• Thesis → Theses
• Analysis → Analyses

This rule is why analyses looks different from just adding an “s.” Remembering its Greek origin can help you avoid errors.
