Somewhat broad; wider than average but not extremely wide.
From 'broad' + the diminishing suffix '-ish' (from Old English -isc), which softens descriptive words to mean 'somewhat' or 'rather.' This pattern applies to countless English adjectives like 'greenish' and 'tallish.'
The '-ish' suffix is one of English's most honest patterns—it admits uncertainty and approximation. No one's really sure exactly how broad something broadish is, and the language just shrugs about it.
