Morphology

adverse = ad + verse

Although historically analyzable as Latin ad- + -verse ('turn'), the element 'verse' meaning 'turn' is not a standalone English word and the classical combining forms are not productive or obvious to typical learners, so the meaning cannot be reliably derived from its parts.

Etymology

Adverse comes from Latin parts ad- ('to') and versus ('turned'), from a root that means 'to turn'. Think of reverse, which has the same 'turn' root: when something is 'turned against' you it becomes harmful or unfavorable, so adverse means 'acting against' or 'harmful'.
