Parent disheartened by call in cellar (5)
I believe the answer is:
crypt
'cellar' is the definition.
(thesaurus)
'parent disheartened by call' is the wordplay.
'disheartened' means to remove the middle letters.
'by' says to put letters next to each other.
'call' becomes 'cry' ('cry' can be a synonym of 'call'**).
'parent' with its middle taken out is 'pt'.
'pt' put after 'cry' is 'CRYPT'.
'in' is the link.
(Other definitions for crypt that I've seen before include "Vault beneath a church" , "Undeground room" , "Underground church vault" , "Church basement" , "Sepulchre" .)
