yesterday I was talking to one of my friend via SKYPE. Correct, We capitalize the first letter of the first word in a sentence Yesterday,
Because she study mandarin and she asked a question about the meaning of one word.
This would be better. She studies Mandarin and asked a question about the meaning of one word. You do not have to repeat she in the sentence as you have already mentioned her studying.
And I have explained to her and then I said:
Does that make sense to you?
I wanna ask few question in here.
1: Can I change the "to" to "for"? If it is okay, What's the difference ? And in what circumstance to use "to" and "for".Not suree what you are asking. Both to and for are prepositions and are not usually interchangeable.
2: Can I say " Is that make sense to you"? Why? No! Does that make sense to you is correct.
