A person asks, “Who is the winner?” The reply is زَيْدٌ
Zayd.
The preceding question makes the intended predication recoverable: the answer means that Zayd is the winner. If an omission instead allows incompatible interpretations with no resolving cue, brevity may become obscure rather than eloquent.
Method: identify what is left unspoken, propose the recoverable construction, and explain precisely which contextual clue licenses the omission.
