Somewhat cranky or eccentric; having the characteristics of a crank.
From crank + -ish (a suffix meaning 'somewhat' or 'like,' as in foolish or darkish). Creates a softer adjective suggesting partial rather than complete crankiness.
Crankish personality traits often cluster together—people who are stubborn about one thing tend to be opinionated about others, suggesting cranky rigidity might be a genuine personality dimension rather than just mood.
