Famous lab dismantled in a minute (7)
I believe the answer is:
notable
'famous' is the definition.
(I know that famous can be written as notable)
'lab dismantled in a minute' is the wordplay.
'dismantled' indicates anagramming the letters.
'in' indicates putting letters inside.
'a minute' becomes 'note' (I can't justify this - if you can you should believe this answer much more).
'lab' with letters rearranged gives 'abl'.
'abl' inserted within 'note' is 'NOTABLE'.
Can you help me to learn more?
(Other definitions for notable that I've seen before include "Worthy of record" , "Worthy of attention, significant" , "Prominent" , "Great" , "Impressive" .)
