/ˌrɛkəˈmɛnd/
[verb] To tell someone that a person, thing, or idea is good or suitable, or to suggest that a particular action should be taken. When you recommend something, you are sharing your positive opinion to help someone else make a good choice.
Every time you recommend something, you are literally placing it into someone else's hands — that is exactly what the Latin root means.
The word 'recommend' reaches back to classical Latin, where two powerful little words were joined together to create a lasting idea. The first is the prefix 're-', which in Latin did not simply mean 'again' but carried the sense of 'back' or 'with intensity'. The second is the verb 'commendare', meaning 'to entrust, to commit to someone's care, to hand over something precious'. So the combined Latin form 'recommendare' described the act of placing something — or someone — into another person's keeping with a sense of confidence and trust.
The Latin root goes even deeper. 'Commendare' itself is built from 'com-' (a prefix meaning 'together' or 'completely') and 'mandare', meaning 'to entrust, to order, to put into one's hand'. That word 'mandare' comes from 'manus' (hand) and 'dare' (to give), so at its very core, to commend — and therefore to recommend — is to literally hand something over. This same root 'mandare' gave English 'command', 'mandate', 'demand', and 'mandatory', all words that carry a sense of authority and placing responsibility in someone's hands.
The word entered Medieval Latin as 'recommendare' and was used in the language of the Catholic Church and formal correspondence, where one person might recommend another to the care of a patron, a bishop, or even to God. From Medieval Latin, the word passed into Middle French as 'recommander', keeping the same meaning of entrusting or commending someone or something to another's favour. English borrowed it from this French form in the late 14th century, during a period when French was still deeply influential in English official and courtly life.
When 'recommend' first appeared in written English, it was used in quite a formal, personal way — you recommended a person to someone else's goodwill, much as you might write a letter of introduction today. Over the following centuries, the meaning slowly broadened. By the 17th and 18th centuries, it had expanded to cover things as well as people, and the idea of 'entrusting' softened into the more general sense of 'suggesting as worthy of attention'. A doctor might recommend a treatment; a friend might recommend a book. The word had moved from the formal world of patronage into everyday conversation.
One of the word's most charming quirks is its spelling, which trips up even experienced writers. The 'cc' in the middle — one 'c' from the prefix 're-' blending with the 'c' that begins 'commend' — creates the double-c that many people mistakenly reduce to a single letter. It is a small fossil of the word's layered history, a reminder that 'recommend' is really 're-' plus 'commend', two pieces fused together. The related word 'commend' remains in English on its own, meaning to praise or express approval, and it reveals the older, simpler layer beneath the more familiar word we use every day.
