Only men can get this notice at a Mississippi tech company (5,5)
I believe the answer is:
adams apple
'only men can' is the definition.
The answer and definition can be both body parts as well as being singular nouns.
Perhaps there's an association between them I don't understand?
'this notice at a mississippi tech company' is the wordplay.
'this notice' becomes 'ad' (both can mean an advertisement).
'at' says to put letters next to each other.
'mississippi' becomes 'ms' (US postal abbreviation for Mississippi).
'tech company' becomes 'apple'.
'ad'+'a'+'ms'+'apple'='ADAMS APPLE'
'get' is the link.
Can you help me to learn more?
(Other definitions for adams apple that I've seen before include "Thyroid cartilage projection in throat" , "Prominence on the throat" , "Fruit from old garden" , "Prominent part of male anatomy" , "External protuberance of part of larynx" .)
