I am preparing for a prestigious examination that opens the doors for becoming a top dog in the government. English plays a vital role in the examination. So, I've started taking lessons from an engineer-turned English teacher. He is quite famous here in India. He was teaching relative pronouns the other day when this particular sentence came up.
The thief stole the little money which he had saved for his daughter's marriage.
The teacher said that it was wrong to use 'Which' and it should be replaced by another relative pronoun 'That'.
The thief stole the little money that he had saved for his daughter's marriage.
I thought that 'Which' and 'That' were perfectly interchangeable in the sentence and it was just the matter of taste. When I asked him, he said that 'That' is used when there is an emphasis on the antecedent. He argued that the phrase 'The little' puts an emphasis on the antecedent 'Money' and hence 'That' was the right choice.
I did not like this weird logic and hence, I want your two cents on it. Please help me.
