Your sentence "italki is a nice language learning hub and I'm quite sure that most of the users must buy into this fact." is not wrong, however, the phrasal verb 'buy into' is usually used in reference to a new idea, a new proposal, or any other new concept.
Normally one would not buy into a fact, since facts are usually based on evidence that compels one to accept the fact, as opposed to one being encouraged, convinced or motivated to accept and support an idea or to completely believe in a set of ideas.
Here are a few more typical uses:
- Many people in the UK bought into the proposition to separate from the European Union.
- She had never bought into the idea that to be attractive you have to be thin.
- You don’t buy into all this nonsense, do you? [this question is not asking if you buy into my explanation :) ]
Does my explanation help? Do you 'buy it'?
Thank you @Richard for some really helpful phrasal verbs:)
"Buy into" is new to me.Let me make a sentence---italki is a nice language learning hub and I'm quite sure that most of the users must buy into this fact.
Another small confusion about "build on" and "build up".Can I use it alternatively? for example--Newspaper really build on/build up your memory.
Please put some light on this.Thank you:)
You have probably used the verb "burn out" because you are a school teacher and teaching in a school can be very demanding physically and mentally.
Your two sentences , using buy up and buy in are good examples.
Thank you for your helpful comments.
I like this discussions a lot!
I find very difficult to use and remember phrasal verbs and seeing them here, helps me to pick up those that I find useful for myself.
I must admit that from this list I have used many times the phrasal verb "Burn out", I wonder why!
However, I didn't know about the verb "Buy" and I think I might use these ones:
There are some companies that buy up a particular product not to let others sell it.
I told my sister about starting a new business together but she didn't buy into my idea.
Thank you so much for these discussions!
