Student or Learner
I just want to confirm about the below mentioned sentences which one is the correct:
1. For which post are you applying for?
2. Are you applying for which post?
To understand the use of “that and which” please note the use of “who”
Who is used for persons (male or female) and which for animals and things. The singular pronoun “that” has a special use. It is used before which in the quite general sense of 'the thing' or 'a thing', with no reference to anything previously mentioned.
Examples: My son who is married is not here.
The bird which takes the fruit is on that tree.
You may take the apples which are on the table.
You may do that which I do.
That is used as a joining word between the verbs like “ say, see” and a statement of what is said in cases where the exact words used by the speaker are not given in quotation marks.
Examples: I say that he will come again.
Your daughter saw that one bottle was broken.
That is also used with nouns such as answer, news, opinion, idea to introduce a statement giving the answer, news, etc., in question.
Examples: My opinion is that he is not a good judge of women
We had an idea that what he was saying was foolish.
