Every single bit of lead stripped before church (4)
I believe the answer is:
each
'every single' is the definition.
(I've seen this in another clue)
'lead stripped before church' is the wordplay.
'stripped' indicates the central letters (outside letters removed).
'before' says to put letters next to each other.
'church' becomes 'ch' (common abbreviation).
The middle letters of 'lead' are 'ea'.
'ea'+'ch'='EACH'
'bit of' acts as a link.
This may not be correct. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for each that I've seen before include "Every one separately" , "every one individually" , "every one of a group" , "Every single one, person or thing" , "...per head" .)
