気味(ぎみ)Looking, Feeling a little, Touch of, Tending to, Slightly

Both ぎみ (often written in kanji as 気味) and っぽい describe tendencies or characteristics, but with different nuance. ぎみ suggests a slight or subtle tendency, often related to physical or emotional states, e.g. 疲れ気味 ('a bit tired') or 風邪気味 ('have a bit of a cold'). っぽい implies a more innate trait that gives the appearance or impression of something, e.g. 子どもっぽい ('childish') or 忘れっぽい ('forgetful').

的 and ぎみ (気味) are similar in that both can be attached to nouns to turn them into adjectives, but they differ in nuance and usage. 的 has a wider range of uses, similar to English endings like '-al', '-ly', etc., e.g. 感情 'emotion' vs. 感情的 'emotional'. In contrast, ぎみ has the specific meaning of 'slightly (A)' or 'showing tendencies of (A)', and typically expresses a subjective judgment about a condition, e.g. 疲れ気味 'a bit tired'.

Both ような気がする and ぎみ (from 気味) use 気 expressions to convey subtle states or impressions, but with different nuance and usage. ような気がする follows a phrase to express a subjective hunch like 'Have a feeling that (A)', e.g. 来るような気がする 'I have a feeling they'll come.' ぎみ attaches to nouns to express a slight tendency or hint of something observable, often (but not always) negative, e.g. 疲れ気味だ 'I'm feeling a bit tired.'

ぎみ (often written in kanji as 気味) and げ both describe observable states, but differ in focus. ぎみ suggests a slight or subtle tendency, often related to physical or emotional states, e.g. 疲れ気味 ('a bit tired') or 風邪気味 ('have a bit of a cold'). げ expresses perceived emotions of others, e.g. 寂しげな顔 ('a lonely-looking face').
