I have a grammatical question. Are we supposed to nasalize chahiye to chahiyeN with a plural? If so, is it when the subject is plural or the object? I feel I have heard some nasal voiced types say chaNhiye or chaNhiyeN. Is that some type of regional accent, or is that the plural? If it is supposed to be nasalized according to the rules, can you kindly give me a very simple sample sentence contrasting the singular with the plural?
