Lament from half of One Direction on record (4)
I believe the answer is:
weep
'lament' is the definition.
(thesaurus)
'half of one direction on record' is the wordplay.
'half of' indicates taking half.
'one' becomes 'me' (a setter might use 'one' to humourously mean 'me').
'direction' becomes 'w' (W is an example**).
'on' is a charade indicator (letters next to each other).
'record' becomes 'ep'.
'me' cut in half is 'e'.
'e' put after 'w' is 'we'.
'we'+'ep'='WEEP'
'from' is the link.
(Other definitions for weep that I've seen before include "Pee-pee" , "Greet" , "pipe" , "Display sorrow" , "Cry, shed tears" .)
