Identify as grass? (4)
I believe the answer is:
tell
This clue might be a double definition.
'identify' is the first definition.
(telling is a kind of identifying)
'grass?' is the second definition.
Although both the answer and definition are verbs in their base form, I can't see how they can define each other.
'as' acts as a link.
Can you help me to learn more?
(Other definitions for tell that I've seen before include "Count - give an account" , "Apprise" , "Relate; Swiss hero" , "Issue instructions" , "William .... was legendary Swiss hero-archer" .)
