Plenty in Glasgow from Spain at this time (4)
I believe the answer is:
enow
'plenty in glasgow' is the definition.
The definition suggests an adverb which matches the answer.
'spain at this time' is the wordplay.
'spain' becomes 'e' (abbreviation for Espana).
'at' means one lot of letters go next to another.
'this time' becomes 'now' (now is a kind of time).
'e'+'now'='ENOW'
'from' acts as a link.
Can you help me to learn more?
(Other definitions for enow that I've seen before include "adequate" , "Old enough" , "Sufficient in the past" , "a moment ago" , "up in Scotland" .)
