Definition - dishonest
Certain nouns take to certain adjectives readily, and, once connected, seem reluctant to let go. There are a handful of things which are considerably more likely to be modified with crooked in its literal sense; smiles, teeth, and streets often are paired with this word. In the sense we are concerned with, “dishonest,” there are specific occupations which are much more likely to be paired with crooked, and these are cop, lawyer, and politician.
The maxim that has been laid down by certain crooked politicians, to behave to a friend with the same guarded caution as we would do to an enemy, because it is possible that he may one day become such, discovers a mind which never was made for the enjoyments of friendship.
— Hugh Blair, Sermons, 1794
