Morphology

ratfink = rat + fink (transparent) = rat + fink

The derogatory meaning is directly built from two insulting nouns that both convey treachery or contempt, so a learner familiar with those components can infer the sense.

Etymology

Ratfink as an insult combines rat (a 'sneaky' or 'traitor'-like animal) and fink (someone who 'tells on others' or is 'despicable'), so calling a person a ratfink is a strong way to say they are treacherous and not to be trusted.
