The Spanish verb 'entregar' (meaning 'to deliver' or 'hand over') comes from the Latin verb 'integrare' meaning 'to make whole' or 'restore'. This Latin verb was formed from 'integer' (meaning 'untouched' or 'whole') which itself contained the negative prefix 'in-'.

The semantic evolution from 'to make whole' to 'to deliver/hand over' likely developed through the concept of completing a transaction or making something complete by transferring it to its intended recipient.

Some related Spanish words include 'íntegro' (meaning 'complete' or 'honest'), 'integral' (meaning 'complete' or 'integral'), and 'integrar' (meaning 'to integrate' or 'to complete'). These words maintain meanings closer to the original Latin sense of wholeness or completeness.

English speakers might recognize the connection to words like 'integral', 'integrate', and 'integer'. While 'entregar' developed to mean 'to hand over', these English cognates maintained meanings closer to the original Latin sense of wholeness - 'integral' means essential or complete, 'integrate' means to make whole or combine, and 'integer' in mathematics refers to a whole number.
