Gave good service about odd way to become known (10)
I believe the answer is:
acquainted
'gave good service' is the definition.
The answer and definition can be both to do with communicating as well as being past participle verbs.
Maybe they are linked in a way I don't understand?
'about odd way to become known' is the wordplay.
'about' means one lot of letters goes inside another.
'odd' becomes 'quaint'.
'way' becomes 'e' (Compass direction - East).
'to become known' becomes 'acd' (I can't explain this - if you can you should give a lot more credence to this answer).
'quaint'+'e'='quainte'
'quainte' going within 'acd' is 'ACQUAINTED'.
Can you help me to learn more?
(Other definitions for acquainted that I've seen before include "on good terms" , "Notified" , "Made aware of" , "Familiar (with)" , "knowing a little" .)
