Does it take flight when it sees a saw? (5,4)
I believe the answer is:
plane tree
'saw?' is the definition.
Although both the answer and definition are singular nouns, I can't see how they can define each other.
'does it take flight when it sees a' is the wordplay.
I cannot really see how this works, but
'it' could be 't' (abbreviation. e.g. in 'tis) and 't' is found in the answer.
'take' could be 'r' (recipe is latin for take - r is abbreviation) and 'r' is located in the answer.
'when' could be 'e' (I've seen this in other clues) and 'e' is found in the answer.
'a' could be 'an' and 'an' is found in the answer.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for plane tree that I've seen before include "growth" , "Common city plant" , "It sheds its bark" , "maple" .)
