The common Spanish word dar (“to give”) comes from the Latin for the same, dare.
From the Latin root, we get the English… mandate (“to give with your hand” – thus related to mano as well): what is a mandate if not a written order to give to someone? The best mandates are when you deliver them yourself anyway, not through intermediaries. The dare connection explains where the -d- after the hand comes from!
Another English word from the same root: tradition. That word comes from the Latin tradere, literally, “to hand over” — the tra– is the same trans- root (“over”), while the dere is the same “give.” In today’s way of walking, we’d say that tradition is what is handed down to us: it is what is given to us. Literally. ANd you can see the -d- in the word from dare as well clearly!
