5. as a non native speaker, what on earth does ‘they’re just things what we’ve used’ even mean? I've read these sentence many times and I still can't figure it out...
Spatula, pot, spoon, bowl.
Those are things that we have used [today to make and eat soup].
For some reason, particularly round my parts, 'that' is often swapped for 'what', e.g. "Places what I've gone to."
