It was at Seoul station that I saw her yesterday.
Which word can be used instead of underlined that?
I think which can be used instead of it. Am I right???
If you're asking whether "which" can used instead of "that", no, you need "that".
Please do quote your example sentences and quoted words. If you put that or which or that which should be quoted in a sentence without quoting that, or which, or how, how can we make sense of this, how or that, or indeed anything at all?
