In a friendly and pleasant manner; in a way that shows you are easy to get along with.
From 'amiable' plus the adverbial suffix '-ly', which comes from Old English 'lice' meaning 'like' or 'in the manner of.' This word maintains the same Latin root 'amicus' (friend) as 'amiable.'
The '-ly' suffix is one of English's most productive word-building tools—you can add it to almost any adjective to describe how something happens, and 'amiably' shows how a simple root about friendship becomes a word for the way people behave.
