Leaving out the "subject" at the beginning of a sentence? I think this mostly concerns spoken English!
Is this considered grammar correct or just a phenomenon that occurs in intimate conversational spoken English?
For example:
- Hey, why are you examining the book?
- (I am) Trying to figure out what to do with it.
Or:
- How are the apples? Have you tried them already?
- (They are) Quite good! Really!
Unfortunately I cannot give sources where I've met such constructions but I can obviously tell you that I've heard them in movies and TV series!
I have analysed the E.L.U. question concerning "Conversational Deletion" and can't understand whether it is considered less formal or not proper English? Can it be used outside spoken English?
