Frustrated husband and daughter grasping electrical unit (8)
I believe the answer is:
hampered
'frustrated' is the definition.
(I've seen this before)
'husband and daughter grasping electrical unit' is the wordplay.
'husband' becomes 'h' (abbreviation).
'and' says to put letters next to each other.
'daughter' becomes 'd' (genealogical abbreviation).
'grasping' indicates putting letters inside (inserted letters are held or grasped).
'electrical unit' becomes 'ampere' (I've seen this in another clue).
'h'+'d'='hd'
'hd' enclosing 'ampere' is 'HAMPERED'.
(Other definitions for hampered that I've seen before include "Blocked" , "Frustrated" , "Hindered, cramped" , "Prevented free movement, restricted" , "Obstructed; handicapped" .)
