MY "COUPLE" WORKS AS AN ENGINEER
This is a very common mistake for Spanish people because they translate directly from Spanish and they think about the words "mi pareja".
The correct version of the sentence above is: "My partner / husband / wife / boyfriend / girlfriend works as an engineer". We do use the word "couple" but we use it in a slightly different context.
For example, you can say: "Do you know if they are a couple?" which is when you are asking whether two people are linked romantically.
The other way we use couple is to talk about "two things". For example: "Can I have a couple of beers, please?" This means that you want 2 beers.
Hope that helps!
