The Spanish verb 'llevar' (meaning 'to carry' or 'to take') comes from the Latin word 'levare', which meant 'to lift' or 'to raise'. This evolved into Old Spanish 'lievo' ('I lift/carry'), before finally becoming the modern Spanish 'llevar'. The change from 'levare' to 'llevar' shows a common Spanish sound change where 'l' became 'll' at the beginning of words, and the 'v' sound was preserved.

Some related Spanish words include 'leve' (meaning 'light' or 'slight'), which comes directly from Latin 'levis' and shares the same root concept of lightness or lifting. Another related word is 'aliviar' (meaning 'to relieve' or 'to alleviate'), which also connects to the original idea of lifting or raising a burden.

English speakers might recognize the connection to words like 'levitate' (to rise or float in the air), 'lever' (a tool used for lifting), and 'alleviate' (to make something lighter or more bearable). All these words share the same Latin root 'levare' and maintain some connection to the original concept of lifting or raising. The semantic shift from 'lifting' to 'carrying' that occurred in Spanish is quite logical, as carrying something typically involves lifting it first.
