People who have the ability to hide a false heart? (4)
I believe the answer is:
clan
'people who' is the definition.
'clan' can be an answer for 'people' (thesaurus). I am not sure about the 'who' bit.
'have the ability to hide a false heart?' is the wordplay.
'have the ability to' becomes 'can' (I've seen this in another clue).
'hide' is an insertion indicator.
'heart?' says to take the centre (I've seen 'heart of' mean this).
The middle of 'false' is 'l'.
'can' placed around 'l' is 'CLAN'.
Can you help me to learn more?
(Other definitions for clan that I've seen before include "Tribe or collection of families under a cheiftain" , "Kinship group" , "Group with a tartan?" , "Large family forming close group, big in Scotland" , "People related by blood and marriage" .)
