It is a happy word. But what a strange word.
It really takes a lot of context to know what is meant by it.
It can mean “perform”. It can mean “reach” a point. It can mean “to honor or praise”.
Something can happen without being a good reason to honor or praise anybody, so it is possible to celebrate something without celebrating it. There are a few events this week that I can think about that would fit that description.
And then there are celebrities. Does that mean they perform? They reached a point? (did they “arrive”?) Or that we honor them?
When you choose words to describe your value, what you contribute, if you cannot be completely unequivocal, at least know what context they have to be heard in and adjust for that.
