seems; somewhat; -ish; easily does~;
Expresses that something seems or is somewhat like something, or that someone tends to do something.
っぽい is a casual but common suffix meaning 'seems', 'somewhat', or '-ish'. When attached to a noun, it suggests that something has the qualities of that noun. For example, 子供っぽい means 'childish', not 'like a child' in a cute way, but rather 'immature'. Attached to a な-adjective stem, it softens the adjective: 大人っぽい means 'mature-looking' or 'seems grown-up'. With verbs, it indicates a tendency to do that action easily or often, like 忘れっぽい meaning 'forgetful' (tends to forget). Note that っぽい is not typically used with ます-stem or て-form; it attaches to the ない-stem of verbs.
