'consuelo' originates from Spanish, specifically the word 'consuelo', where the element 'con-' meant 'with' and the root derives from Latin 'consolāre' meaning 'to comfort or console'.

'consuelo' derives from Latin 'consolāre' (to soothe, to comfort), passed into Old Spanish as 'consuelo' and remained in modern Spanish; English borrows the Spanish word as a loanword or proper name.

Initially related to the action 'to console' (to soothe or comfort), over time it came to be used as a noun meaning 'a consolation or source of comfort' and as a personal name.
