There were three uses of the word I was able to replace.
Use ‘it’ instead
“Where is that?” became “Where is it?”
Use ‘the’ instead
“Where is that newspaper?” became “Where is the newspaper?”
Delete ‘that’ completely
“She realised that she used it too often.” became “She realised she used it too often.”
By using these replacements, I was able to remove almost half of my ‘that’s and the WIP reads much better for it.
I didn’t realise that I used that word so often. Now I know that, I can eliminate that and that’s a good thing.
