> Natural languages balance between regular rules (e.g. in English, we often add -ed to make the past tense of a verb) and exceptions especially for common cases ("went", "was", "had", "made", "did" because going, being, having, making, doing are all so common).

Yes, but different natural languages resolve this tension differently.

For example, Turkish is much more regular in its verbs (and in general) than English or German.
