I am wondering if there is a term for this circumstance we have with a specific word in French.

The word PLUS means both ''more'' and ''no more'' - completely opposite meanings for the same word. Sometimes, you'll see advertising with this word and it's always a bit of an issue whether they mean one or the other.

For example, an insurance company is currently using it. They meant to say that with their policy you have more money in your pocket when you put in a claim, but people are laughing and saying that it's the first time an insurance company is being truthful by telling you you'll have no more money in your pocket.

Do you know of any word like this in English. What would this be called?
