The action or process of antagonizing someone; the state of becoming hostile or opposed to something or someone.
From antagonise plus the suffix -ation (from Latin -atio), which transforms verbs into nouns denoting an action or process; primarily British English spelling.
The word 'antagonisation' acknowledges that hostility is often a process, not an instant spark—social scientists use it to describe how small provocations accumulate into larger conflicts, like rocks rolling downhill!
