Making a loud noise; characterized by or full of din or clamor.
From Middle English 'din' + suffix '-some' (characterized by), likely formed in the 14th-15th centuries following the pattern of words like 'fearsome' and 'loathsome.'
This is an archaic gem showing how English speakers once freely combined '-some' with nouns to create descriptive adjectives—you could make 'fruitsome' or 'pranksome' the same way, though only a few survived into modern English.
