Prestar (Spanish for “to lend”) has its English equivalent in… presto!
There is a deeper connection. Both come from the Latin praesto, meaning, “ready”, which also came to mean, “provide”. Provide, over the years, turned into “lend” as Latin evolved into Spanish: the lender is the provider, after all. Thus, “ready” turned into “provide” which turned into “lend”!
From the same Latin root, we also get the English press–but not in the common sense of pressing a button. But in the almost forgotten, more esoteric sense of forcing into military service. I remember learning in an 18th century British history class that the British crown used the impress men into military service–no, they weren’t trying to impress them (make yourself sound great) but instead to impress them (draft them!). This press and impress, in these particular senses, also come from praesto.
