Young woman getting over stockholder? (5)
I believe the answer is:
lasso
'stockholder?' is the definition.
(I've seen this in another clue)
'young woman getting over' is the wordplay.
'young woman' becomes 'lass' (informal term for a young woman).
'getting' means one lot of letters go next to another.
'over' becomes 'o' (cricket abbreviation).
'lass'+'o'='LASSO'
(Other definitions for lasso that I've seen before include "Looped rope used to catch cattle" , "Cow catcher" , "One may be caught by this" , "What cowboy uses" , "snare" .)
