How to Say "With" in Latin - How To Say Guide

cum

[ˈkũː]

The Latin word for "with" is cum.

cum is used to mean "with", "together with" or "along with".

Meaning: with (prep)

How does it change in a sentence?

The preposition cum must be followed by a noun in the ablative case.

Avoid using the accusative case after cum. You must use the required ablative case instead.

While cum means 'with', it is distinct from the word used for 'by means of'. To say 'with a hammer', a Roman would use the ablative case alone without the word cum.
If you see 'cum' used in a legal or formal English term, it is often acting as a Latin preposition meaning 'along with' or 'combined with', such as in the phrase 'magna cum laude'.
The Latin cum is a distant relative of the English prefix 'co-' as in 'cooperate' or 'coexist'. Both originate from a Proto-Indo-European root meaning 'with' or 'along'.
