I am a non-native speaker of English.
When I do not understand a word (because I have never seen it before for instance), I look it up in a dictionary. The dictionary will give me the meaning and hopefully everything will be clear.
I also face the case where I am not sure about the actual usage of a word. This is typically the case in What is the contemporary meaning of "consensual"?.
Since I understand, "dictionary-speaking", what this word means, I specifically ask about native speakers use this word today.
How can this not be "opinion-based"?
If such questions are out of scope - why is there the word "Usage" in the name of the site?
