Are यह and ये interchangeable?
No they’re not - the first is singular and the second is plural. However, in colloquial Hindi, they are pronounced the same - “ye”. When learning, though, you want to distinguish the sounds.
What about वह and वे? Colloquially, I know the former is pronounced "vo", but is वे pronounced "ve" or "vo" (again, colloquially)?
Plural is pronounced "vē".
Why not "this is an apple"??
Because ये is plural. "This is an apple" = "यह सेब है"
Notice that हैं differs from है. The former is used in plural and the latter in singular.
Thank you ,you clear me !
Because this is plural
Because there is a small dot above 'hai' you can see
Does Hindi use the same word for 'apples' as for 'apple'? (No distinction between singular and plural?!)
Correct. Same as English with words like "fish" and "sheep".
