Clot aunt again dispersed, using this? (13)
I believe the answer is:
anticoagulant
'this?' is the definition.
The definition suggests a singular noun which matches the answer.
'clot aunt again dispersed' is the wordplay.
'dispersed' is an anagram indicator.
'clot'+'aunt'+'again'='clotauntagain'
'clotauntagain' anagrammed gives 'ANTICOAGULANT'.
'using' acts as a link.
Can you help me to learn more?
(Other definitions for anticoagulant that I've seen before include "Blood-thinning agent" , "Substance that prevents blood clotting" , "Blood clotting retarder" , "Blood thinner" , "Drug hindering blood clotting" .)
