Reach and grab a shirt tail (3,2)
I believe the answer is:
get at
This could be a double definition.
'reach' is the first definition.
(I know that get at is a type of reach)
'grab a shirt tail' is the second definition.
'get at' can be an answer for 'grab' (thesaurus). I'm not sure about the 'a shirt tail' bit.
'and' is the link.
Can you help me to learn more?
(Other definitions for get at that I've seen before include "Nobble; gain access to" , "Unfairly influence" , "Pick on - gain access to" , "Intend" , "Reach - mean - attack verbally" .)
