Two-way air traveller? (4)
I believe the answer is:
bird
'air traveller?' is the definition.
The definition and answer can be both people as well as being singular nouns.
Maybe there's a link between them I don't understand?
'two-way' is the wordplay.
'two' becomes 'bi' (I can't justify this - if you can you should give a lot more credence to this answer).
'way' becomes 'rd' (short for road).
'bi'+'rd'='BIRD'
Can you help me to learn more?
(Other definitions for bird that I've seen before include "Charlie "___" Parker - time inside" , "Flying creature" , "Nest builder?" , "Egg-laying creature" , "Prison sentence - hawk, perhaps" .)
