Finally visiting relative, allowed protective clothing (8)
I believe the answer is:
gauntlet
'protective clothing' is the definition.
'gauntlet' can be an answer for 'clothing' (gauntlet is a kind of clothing). I'm not sure about the 'protective' bit.
'finally visiting relative allowed' is the wordplay.
'finally' says to take the final letters.
'relative' becomes 'aunt' (aunt is a type of relative).
'allowed' becomes 'let' (to let is to allow or permit).
The last letter of 'visiting' is 'g'.
'g'+'aunt'+'let'='GAUNTLET'
Can you help me to learn more?
(Other definitions for gauntlet that I've seen before include "Throw it down to offer a challenge" , "that may be punishing for runner" , "Glove with long sleeve, thrown down challenge" , "Knight's glove" , "outdated military punishment" .)
