Deviating from or opposed to established rules, regulations, or normal patterns.
From Latin 'contra' (against) + 'regular' (from 'regula,' rule). A formal term from academic and administrative contexts.
In languages, contraregular verbs are the ones that break all the rules—like 'go' becoming 'went' instead of 'goed'—and they tend to be the oldest, most frequently used words!
