Traditional roof in which church? (6)
I believe the answer is:
thatch
'traditional roof' is the definition.
'thatch' can be an answer for 'roof' (thatch is a kind of roof). I'm unsure of the 'traditional' bit.
'which church?' is the wordplay.
'which' becomes 'that' ('that' and 'which' are often synonymous).
'church?' becomes 'ch' (common abbreviation).
'that'+'ch'='THATCH'
'in' is the link.
Can you help me to learn more?
(Other definitions for thatch that I've seen before include "Roofing material - thick hair" , "Alternative to lead roof" , "Reed roof-covering" , "Old roof covering for house" , "nothing of interest to thief wanting roof lead" .)
