Take hold of, grab (5)
I believe the answer is:
seize
This clue is a double definition.
'take hold of' is the first definition.
(I've seen this in another clue)
'grab' is the second definition.
(I know that grab is a more specific form of the action seize)
(Other definitions for seize that I've seen before include "square in Paris" , "Get hold of" , "Impound" , "Grab by force" , "Suddenly take hold of" .)
