necessitate
Make absolutely required
Necessitate means to make something necessary or unavoidable.
Circumstances necessitate action; requirements necessitate compliance.
The flood damage necessitated extensive repairs.
The word carries a sense of compulsion—not merely suggesting but forcing a particular response or outcome.
It's slightly formal, more common in writing than speech.
