Container receipt missing one parcel we oddly overlooked (10)
I believe the answer is:
receptacle
'container' is the definition.
(I know that receptacle is a type of container)
'one parcel we oddly overlooked' is the wordplay.
'one' becomes 'recept' (I can't explain this - if you can you should believe this answer much more).
'oddly overlooked' indicates alternate letters (letters in odd-numbered positions removed).
'parcel'+'we'='parcelwe'
The alternate letters of 'parcelwe' are 'acle'.
'recept'+'acle'='RECEPTACLE'
'receipt missing' acts as a link.
This may not be correct. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for receptacle that I've seen before include "Object made to contain something" , "bin, perhaps" , "What may contain something" , "Holder" , "Container" .)
