2.2.1.4. Null arguments for subject and object
LSC is characterized as a null-subject language: when the subject or the object of a sentence are clearly recoverable by other morphological means (agreement, for instance) or by the linguistic context, they may be omitted. In the example below, signer (A) asks a question to signer (B), namely, if he wants ice-cream. Since they are the only two signers in the context, and the eye gaze of signer (A) is addressed towards signer (B) when uttering the question, it is not possible that they are referring to a third person, thus it is possible to drop the subject. Moreover, in the answer, signer (B) also drops the object, since it is clear from the previous question.
A: (ix2) ice-cream want?
‘Do you want ice-cream?’
B: (ix1)want.
‘Yes, I do.’
