Canada's flag contains a leaf. I want to ask what tree that leaf belongs to using preposition "of" instead of the verb "belong". Can I ask like this:
- What tree does Canada's flag contain a leaf of?
- What tree is it a leaf of on Canada's flag?
Canada's flag contains a leaf. I want to ask what tree that leaf belongs to using preposition "of" instead of the verb "belong". Can I ask like this:
The people who have answered using phrases like a leaf from which tree are giving you English. But as far as I'm concerned none of them is everyday English.
I would say, almost like your question
Which tree does the Canadian flag show a leaf from?
(Your "what" and "of" are both possible, but this is a more natural form, to my ear).
Your second sentence is grammatical, but confusing to read.
A more natural way to ask this: "What kind of leaf is on Canada's flag?" Or even: "What leaf is on Canada's flag?" People should understand this given that different kinds of leaves come from different kinds of trees.
Canada's flag contains a leaf of which tree?
However, I would probably say,
Canada's flag contains a leaf from which tree?
