The Spanish verb 'maridar' comes from the Latin verb 'maritare', meaning 'to marry'. The Latin 'maritare' itself was derived from 'maritus', meaning 'husband'. This evolution shows how the concept of marriage was closely tied to the role of the husband in Latin-speaking societies. The Spanish word maintained both the form and meaning of its Latin ancestor, with minimal changes in pronunciation.

A closely related and more common Spanish word is 'marido', meaning 'husband', which comes from the same Latin root 'maritus'. While 'maridar' refers to the act of marriage, 'marido' refers to the male spouse, preserving the connection between these related concepts just as in Latin.

While English 'marry' and 'marriage' are related concepts, they actually come from a different Latin root. However, English has preserved some words from the same Latin family as 'maridar' in more formal or legal terms like 'marital' (relating to marriage) and 'maritime law' (where 'maritime' originally referred to marriage to the sea, a concept in naval law).
