“Lost in translation” means the original meaning is changed, weakened, or misunderstood when something is translated from one language to another. It can also be used more broadly when a message gets misunderstood between people or cultures.

Example: a company signs an international contract where the English clause says the supplier must deliver by Friday, but in translation, it becomes may deliver by Friday. That small shift can change a binding obligation into an optional one, creating a dispute over breach of contract.

In business terms, the deal may stall or cost money; in legal terms, the wrong wording can weaken the case, trigger a lawsuit, or even make part of the document hard to enforce.
