Why the verb 'are' is missing in this news headline:
Face Masks Mandatory in All Public Spaces.
Why it is not something like: 'Face Masks Are Mandatory in All Public Spaces'.
I checked by using Google and the 'Face Masks Mandatory in' form is much more common than the 'Face Masks are Mandatory' Why? Where is the verb in this sentence? The word 'mandatory' is an adjective, isn't it?
