homo (Latin)

Where does "homo" come from?

The Latin noun 'homo', meaning 'a human being' or 'man', descends from the earlier Latin form 'hemō'[1]. This earlier form derives from Proto-Italic '*hemō', which traces back to the Proto-Indo-European '*ǵʰm̥mṓ'[1]. This ancestral Indo-European form literally translates to 'earthling' and is built upon the root '*dʰéǵʰōm', meaning 'earth'[1]. This deep root also connects to other historical cognates across Indo-European languages, such as Old Lithuanian 'žmuõ', Gothic 'guma', and Old English 'guma', all sharing the meaning of 'man'.

Open questions

The derivation from Proto-Indo-European involves a phonetic by-form reflected also in Germanic. [3]
Alternative reconstructions of the root suggest a voiced unaspirated velar based on Sanskrit and Anatolian evidence. [4]
