What's the difference between "grammatical mistake" and "grammatical error"?
Based on Cambridge dictionary:
Mistake: an action, decision, or judgment that produces an unwanted or unintentional result.
Error: a mistake.
Does it mean that I can use both (grammatical mistake and grammatical error) interchangeably and they are just synonyms or a matter of taste?
The context is for example when I see that there's no an article in a place where it should be
(e.g. "He took table." instead "He took a table") or when I see missing of s' in 3rd person singular verb in present simple tense
(e.g. "He learn English" instead of "He learns English") etc. and I want to say that it is a grammatical error / mistake.
Google Ngram viewer shows much more results for grammatical error, does it say that it is favorable in my context too?
