A few days before Chinese New Year, street hawkers will start selling "spring couplets" or other festive merchandise along the streets.
Is "the streets" an idiom? Therefore, "the" has to be used?
Thank you so much.
Actually, there is not necessarily any idea that the selling is done at a specific location. In the street is used for any of several ideas: in public, in the open air, not indoors, not in a shop. Street is more commonly used in the singular form, but the plural form, as in panicmonger's sentence, is possible. We do not normally omit the.In the streets is not an idiom, it is a description. The article "the" is used because the selling takes place in a specific location, along the streets.
