The plural of 'analysis' is:

**The reasoning** This follows a pattern from Greek and Latin plurals that English borrowed. Words ending in **-sis** (like analysis, thesis, crisis) change to **-ses** in plural. The rule: **-sis → -ses** So: analysis → analyses (pronounced "uh-NAL-uh-seez") Other examples: - thesis → theses - crisis → crises - hypothesis → hypotheses **Why the wrong options tempt you** **A) Analysises** — This applies the regular English plural rule (add -es), but "analysis" isn't a regular English word — it's borrowed from Greek, so it keeps its original pattern. **C) Analysis** — Looks like you're keeping it the same for both singular and plural (like "sheep"), but analysis *does* change. **D) Analysi** — This chops off letters randomly with no grammatical basis. **Quick takeaway** When you see a fancy word ending in **-sis**, remember: its plural ends in **-ses**. Think "crises happen when you face multiple crises" — same pattern for analysis, thesis, and their cousins.
