The Spanish verb 'nacer' (meaning 'to be born') comes from Late Latin 'nascere', which developed from Classical Latin 'nasci' and earlier 'gnasci', all meaning 'to be born'. The evolution from 'gnasci' to 'nacer' shows a common pattern where the initial 'g' was dropped and the Latin infinitive ending '-i' eventually became '-er' in Spanish.

Some related Spanish words include 'nacimiento' (birth), 'natal' (natal, relating to birth), and 'nativo' (native). These words all share the same Latin root and form a family of words relating to birth and origin.

English speakers might recognize this root in words like 'nascent' (just coming into existence or beginning to develop), 'native' (born in a particular place), and 'natal' (relating to birth). The word 'renaissance' also contains this root - it literally means 're-birth' from Latin 're-' (again) + 'nasci' (to be born). Understanding this connection can help remember that 'nacer' is about coming into existence or being born.
