Having the characteristics of or resembling Frisia or its culture; somewhat Frisian in nature.
From 'Fries' (pertaining to Frisia) plus the suffix '-ish' (Old English 'isc', meaning of, relating to, or somewhat). The '-ish' suffix often conveys 'somewhat' or 'approximately.'
The '-ish' suffix does something interesting—Frisian is the standard adjective, but Friesish suggests something more ambiguous or approximate, like how 'reddish' is different from 'red.'
