Reconstruction:Proto-Germanic/hamfaz

Possibly, via an earlier sense “bent (out of shape), crooked”, from a Proto-Indo-European root meaning “to bend, curve”, but the reconstruction is disputed:

• *kámpos (“bent, curved”), whence perhaps also Latin campus (“field”) and Proto-Slavic *kǫpъ ~ *kǫpa (“hill, island ~ clump, thicket; tassel”),^[1] apparently extended in *-p- from a root *kam-: compare Latin camur (“curved, bent, crooked”), Sanskrit क्मरति (kmárati, “to be curved”) (< *kam-er-);
• *kómpos (id.), from a root *kemp-: compare Latvian kùmpt (“to be(come) bent”), Lithuanian kum̃pas (“curved”), Proto-Celtic *kambos (“twisted, crooked, bent, curved”) and possibly Proto-Germanic *huppōną (“to turn back, retreat”).^[2][3]

In either case, considered cognate with Lithuanian kam̃pas (“corner”), Ancient Greek κάμπτω (kámptō, “to bend, bow, curve”) and Ancient Greek καμπή (kampḗ, “bend”). Derksen, maintaining the former etymology,^[4] supposes the u-vocalism of Lithuanian kum̃p- is secondary.^[5]
