Resembling or befitting a cur (mongrel dog); base, cowardly, bad-tempered, or disloyal.
From 'cur' (a mongrel or inferior dog, used as an insult) plus the suffix '-ish' (meaning like or somewhat). The word reflects medieval attitudes that associated mongrel dogs with undesirable qualities.
Medieval and Renaissance people used 'currish' as an insult precisely because they saw dogs as uncontrolled, disloyal, and base animals—it's a forgotten word that shows how differently historical people viewed dogs compared to today.
