What are “habitual mistakes” when speaking English? They are minor grammar mistakes made when speaking that (usually) do not interfere with communication. A student asked, “Does it matter if I say ‘I went to there’ and not ‘I went there’?” I said yes and no.
No, it doesn’t matter if you want to be understood, the meaning is exactly the same.
Yes, it does matter if you want to be fluent or near-fluent because the “to” hits the native ear like a verbal brick wall.
If you want to become fluent then correct these mistakes earlier, otherwise they will become habitual and it will be much harder to correct them when speaking.
