Attached to a noun or verb stem to mean 'showing a slight tendency toward / a touch of X.' It expresses that someone or something has a faint sign or inclination of a condition, usually mild and often slightly negative (a bit tired, slightly feverish, running a little late). Read as ぎみ when suffixed.
[Noun / Verb ます-stem] + 気味(ぎみ)

疲れ (stem of 疲れる) + 気味 = 'a touch of tiredness.'
風邪気味なので、今日は早く帰ります。
Kaze-gimi na node, kyō wa hayaku kaerimasu.

風邪 (Noun) + 気味 = 'a slight cold'; treated like a な-adjective (風邪気味な).

• Behaves like a な-adjective/noun (風邪気味の人, 疲れ気味な様子). • Usually mild and slightly negative in nuance. • Common set phrases: 風邪気味, 疲れ気味, 遅れ気味, 太り気味, 緊張気味. • Register: neutral; very common in daily speech.
The JLPT rarely asks whether you recognise a pattern — it asks which of several similar patterns fits. These are the ones ~気味 is tested against.
っぽい means 'has the quality of / -ish' broadly (子供っぽい 'childish'); 気味 specifically means a slight tendency toward a (often physical/temporary) condition.
がち means something happens frequently or is a habitual tendency ('tends to, often'); 気味 describes a faint present sign or slight inclination, usually a mild degree.
