Advance slowly under His roof? (4)
I believe the answer is:
inch
This might be a double definition.
'advance slowly' is the first definition.
(I've seen this before)
'under his roof?' is the second definition.
Although both the answer and definition are singular nouns, I don't understand how they can define each other.
Can you help me to learn more?
(Other definitions for inch that I've seen before include "Move in tiny increments" , "make slow progress" , "Rare bird follower" , "Creep, edge" , "Move along gradually" .)
