⚫︎胴体 (どうたい) Translation: Body, trunk (of an airplane, etc.) ⚫︎胴着 (どうぎ) Translation: Body garment, often referring to a type of uniform or training wear. ⚫︎胴回り (どうまわり) Translation: Waist measurement, circumference of the body.

The kanji 胴胴 is a phono-semantic compound (形声文字 けいせいいもじ). The semantic component is 月 (つき, meaning "flesh" or "body") and the phonetic component is 同 (どう, meaning "same"). This suggests that it originally depicted the physical body of a person. The character's evolution from its original pictographic form reflects its meaning of body.
