It helps one get up from sunlit mat abroad (9)
I believe the answer is:
stimulant
'it helps one get up' is the definition.
The definition suggests a singular noun which matches the answer.
'sunlit mat abroad' is the wordplay.
'abroad' indicates anagramming the letters.
'sunlit'+'mat'='sunlitmat'
'sunlitmat' anagrammed gives 'STIMULANT'.
'from' acts as a link.
Can you help me to learn more?
(Other definitions for stimulant that I've seen before include "Means of prompting action" , "Tonic, pick-me-up" , "Drug to make one more vigorous and active" , "Energizer" , "A drug or drink to make one more active" .)
