Frequently asked questions about weigh up
Is weigh up formal or informal?

What is the difference between weigh up and weigh in?
Weigh up is the private act of judging something before deciding, as in weighing up two offers. Weigh in is public: it means joining a discussion with an opinion, usually with on, as in weighing in on the plan. One is thought and the other is speech, which is why the two are easy to mix up.
Can you weigh up a person?
Yes. To weigh someone up is to form a view of their character, skill or trustworthiness, as a coach weighs up a new player. The sense is real and common, though a little informal.

Is it weigh up or weight up?
