Could be Alec from Mechlin (4)
I believe the answer is:
lace
'mechlin' is the definition.
Both the answer and definition are singular nouns.
Maybe they are linked in a way I don't understand?
'could be alec' is the wordplay.
'could be' indicates an anagram.
'alec' with letters rearranged gives 'LACE'.
'from' is the link.
Can you help me to learn more?
(Other definitions for lace that I've seen before include "Spike - ornamental fabric" , "Shoe string" , "Famous play ''Arsenic and Old . . . .''" , "Shoe tie" , "Fortify with spirits; open fabric" .)
