Inclined to chat; talkative or sociable in a friendly, conversational way.
From chat (Middle English, possibly from Old English chatter or related to onomatopoeia) plus the suffix -some meaning 'characterized by' or 'full of.' The -some suffix creates adjectives describing qualities or tendencies.
'-Some' is an underrated suffix that creates personality descriptors—chatsome, handsome, tiresome. These words reveal how English speakers cluster traits together linguistically, making personality a kind of texture.
