human

The word 'human' entered English in the late Middle English period from Old French humain, umain, which itself derived from Latin hūmānus. This Latin adjective is believed to be related to homō, meaning 'man' or 'human being'. A compelling theory connects hōmō to the Latin humus, meaning 'earth' or 'ground', suggesting an ancient conceptual link between humanity and the earth from which we are made. Over time, hūmānus evolved in meaning from simply 'of man' to also encompass qualities considered proper to mankind, such as kindness and refinement, giving rise to the related word 'humane'. The modern English term 'human' retains the core sense of pertaining to the species Homo sapiens.

The word 'human' is a simplex loanword from Latin. It does not contain separable morphemes in its modern English spelling that are productive for analysis (e.g., 'hu' and 'man' are not meaningful morphemes in this context). Its core is the Latin root hūmānus.
