How to know the commonality degree of a given phrase?
We encounter a lot of phrases/expressions on a daily basis:
- What's up
- It's up to you
- It's your call
How do we know which one is more common?
One might hear a phrase in a movie, and enjoy that seen and based on some cognitive bias believe it's a common phrase. He perceives it as common, because of his joy. In fact, one phrase might be rare and we percieve it as common and use it a lot in our idiolect. Do we have objective measures to find out which phrase is more common than the other?
You could do a comparative quantitative search of the phrases on Google's ngram, but this would apply only to literature.
