For instance, there's been a couple of words and phrases whose meaning I have been able to intuitively guess, but couldn't find on places like the Oxford Dictionary or the Merriam-Webster, and so on.
e.g - [...] then said it was too close to call before finally calling it for the Texas governor. (Source: History.com)
Meaning: Predicting that the Texas governor would win.
Now I wasn't able to find a matching definition for the word 'Call' on either of the aforementioned dictionaries, nor could I find a phrasal verb or something similar, but of course, I could be wrong.
The point is, should I learn certain words and phrases like this or not?
There are alternatives of course, asking a native speaker what it means, asking for clarification on a website like this, but wouldn't it get tedious? especially since you never know when you might stumble across a word or phrase like this, and because I am scared in general to ask questions like this on the internet.
Oh and by the way, if this is the wrong place to ask let me know please, and I'll remove it.
