Informed Ohio about drug manufacturing centre there (6)
I believe the answer is:
toledo
'centre there' is the definition.
The definition suggests a singular noun which matches the answer.
'informed ohio about drug' is the wordplay.
'informed' becomes 'told' (telling is a kind of informing).
'ohio' becomes 'o'.
'about' means one lot of letters goes inside another.
'drug' becomes 'e' (e is another name for ecstasy).
'told'+'o'='toldo'
'toldo' enclosing 'e' is 'TOLEDO'.
'manufacturing' acts as a link.
Can you help me to learn more?
(Other definitions for toledo that I've seen before include "Spanish city known for swordmaking" , "Covering, hiding" , "Sp. city, former Visigoth and Castilian capital" , "Spanish city, famous for steel and swords" , "Blade" .)
