The Origin of Analysing or Analyzing
The words analysing and analyzing come from the verbs analyse and analyze, which trace their roots back to the Greek word analysis, meaning to break apart or examine closely. The term later passed through Latin before becoming part of the English language.
Today, both spellings are accepted because British English and American English developed different spelling conventions.

In British English, the verb is usually written as analyse, and its present participle is analysing.
This spelling follows the traditional -ise and -ising pattern used in many British publications.
Examples include:
- Organise → Organising
- Realise → Realising
- Recognise → Recognising
- Analyse → Analysing
Many British publishers, universities, and newspapers use this style.
