Morphology

trimonthly = monthly (semi-transparent) = tri + month + ly

The form is transparently tri- + monthly, but the word is commonly ambiguous (can mean both 'every three months' and 'three times a month'), so learners may be unsure which interpretation applies.

Etymology

Trimonthly is made of tri- ('three') and monthly ('every month'), so a helpful way to remember it is that the word connects the number three with months. That's why trimonthly can mean either 'every three months' or 'three times in a month', depending on the context.
