For (/fɔ:(r)/) is an English preposition.

For has obvious cognates in other related languages including both other Germanic languages, e.g. German (für), Dutch (voor), and romance languages, e.g. French (pour), Spanish (por and para), etc. However, usage is often different and "for" in English may translate to a different preposition in another language.

It has a reduced form /fə(r)/ - sometimes written "fer" to imitate speech.
