Take covering off books Henry introduced to relative (8)
I believe the answer is:
unclothe
'take covering off' is the definition.
I can't judge whether this defines the answer.
'books henry introduced to relative' is the wordplay.
'books' becomes 'OT' (abbreviation for Old Testament).
'henry' becomes 'H' (symbol for the unit of electrical inductance).
'introduced to' indicates putting letters inside.
'relative' becomes 'uncle' (uncle is a kind of relative).
'ot'+'h'='oth'
'oth' going into 'uncle' is 'UNCLOTHE'.
Can you help me to learn more?
(Other definitions for unclothe that I've seen before include "Strip (someone)" , "Reveal" , "shed" , "lay bare" , "set garments aside" .)
