In a bushy manner; in a way that is thick, dense, or full of bushes.
From 'bushy' + '-ly' (adverb suffix). The '-ly' suffix comes from Old English 'líc' (like, similar to), transforming adjectives into adverbs that describe how something happens.
The '-ly' suffix is one of English's most productive word-builders—it transforms almost any adjective into an adverb, and this flexibility is why English can generate new adverbs easily without strict rules the way other languages do.
