The Spanish verb 'cantar' (to sing) comes from the Latin verb 'cantare', which was a frequentative form of the Latin verb 'canere', also meaning 'to sing'. A frequentative form in Latin indicates a repeated or intensive action, so 'cantare' emphasized the ongoing or repeated nature of singing. As Latin evolved into Spanish, 'cantare' naturally developed into 'cantar', maintaining its meaning of 'to sing'.

Several common Spanish words are derived from 'cantar', including 'canto' (song), 'cantante' (singer), 'canción' (song), and 'cantautor' (singer-songwriter). All these words share the same root relating to singing or musical performance.

English speakers might recognize the connection between 'cantar' and words like 'chant', 'enchant', and 'cantata', which all come from the same Latin root. 'Chant' refers to rhythmic speaking or singing, while 'enchant' originally meant to cast a spell through singing or chanting, though it now more generally means to delight or charm. A 'cantata' is a musical composition meant to be sung.
