scranky

(UK, Scotland, dialect) scrawny.

A Scottish and northern English dialect word for scrawny — thin, bony, and underfed-looking. Scranny captures that particular kind of leanness that suggests hardship or neglect rather than athletic fitness. Used for people, animals, or plants that look like they haven't had enough of anything. It has a slightly rougher, more critical edge than 'slim' but less clinical than 'underweight.'

(archaic) A thin or scrawny person or animal.

(colloquial, chiefly, UK) Thin, meagre; unkempt.

(UK, dialect, archaic) Mischievous; vicious; dangerous.
