Idioms That Begin with Prepositions

There are hundreds of idioms that begin with prepositions in English. Idioms are phrases that, taken literally, would either make no sense at all or have an entirely different meaning from the idiomatic definition. “On the other hand,” for example, could literally mean that there is something sitting on your hand, but as an idiom, it refers to an alternative. “At a loss,” on the other hand, doesn’t make much sense at all if you try to explain it using the literal meaning of each word; it only makes sense taken as a whole––as an idiom.

The following list is by no means an exhaustive list of idioms that begin with prepositions. It is, however, a litany of very commonly used idiomatic phrases.
