Ok, then could you tell another word to mean "I don't know a wide range of words to explain what I think in my mind, so I don't know exactly how to explain what I am intending".
Also, you can give me any other words upon your thinking.
I didn't intend to use the word "mould" in my original sentence. I didn't know which word should I use while I was writing it, so I used "mould" just in passing.
