Analysing or Analyzing – Quick Answer

The word comes from the Greek word “analysis”, meaning “a breaking up or examining closely.” It entered English through Latin and French.
Originally, English did not have strict spelling rules. Over time:
- British English kept the older style → analysing

This change happened during the 18th–19th centuries when American lexicographers like Noah Webster reformed English spelling to make it simpler and more consistent.

Key Rule:
- UK English → analysing, organising, summarising
- US English → analyzing, organizing, summarizing
