so if you interchange ik and heb, as in 'heb ik...' or in another phrase 'heb jij', does it turn the sentence into a question? or can you just use them in sentences like 'i have' and 'you have'?
Interchange means turning the sentence into a question ;)
Why ' Have I dishes?' Doesn' t work?
As far as I am aware in English that sentence needs 'do'. But why that is, is probably something that is better explained in the English section of Duolingo
In English you always have to say "Do I have ...?", never "Have I ...?", even though that was often the construct in the past.
Yes, if you're going to say "Have I", it must be followed by "any", as in "Have I any plates?, though as you said, it's incredibly archaic.
its a colloquialism in some places
Why I can't say Do I have ANY plates??
