Fragment of song one should quickly grasp (6)
I believe the answer is:
snatch
This might be a double definition.
'fragment of song' is the first definition.
(I've seen this before)
'grasp' is the second definition.
(I've seen this before)
'one should quickly' is the link.
This may not be correct. Some or all of it may belong to one of the definitions.
Can you help me to learn more?
(Other definitions for snatch that I've seen before include "American kidnapping" , "Appropriate" , "Quickly grasp - fragment of song" , "Grab hurriedly or violently" , "Seize - fragment of verse" .)
