SHOPPING!
There’s a mistake here:
“I went to shopping.”
This is correct:
“I went shopping.”
In English, some activities are said with the following structure:
(form of GO) + (VERB)ING
GO + SHOPPING
GO + HIKING
GO + CAMPING
…etc.
A native speaker might also say:
DO + SOME + SHOPPING
DO + A LOT OF + SHOPPING
(form of DO) + (quantifier) + (VERB)ING
Both are correct:
“I went + shopping.”
“I did + some + shopping.”
Here are some other examples:
We wanted to go + shopping before lunch.
She’s going + shopping later today.
I did + quite a bit of + shopping last weekend.
Let’s go + camping next weekend.
It was a great trip. We did + a lot of + hiking.
I hope this was helpful!
