Talk to Egyptian engineer. The one named on the envelope (9)
I believe the answer is:
addressee
'one named on the envelope' is the definition.
I can't judge whether this defines the answer.
'talk to egyptian engineer' is the wordplay.
'talk to' becomes 'address' (I've seen this in another clue).
'egyptian engineer' becomes 'ee' (this might be a standard abbreviation I've not previously seen).
'address'+'ee'='ADDRESSEE'
'the' is the link.
Can you help me to learn more?
(Other definitions for addressee that I've seen before include "Recipient of post" , "One sent letter" , "Intended recipient of letter" , "The one to whom the message is sent" , "Person whose name is on the envelope" .)
