Hanging underneath leg, sway (2,4)
I believe the answer is:
Here is my best explanation:
'hanging' is the definition.
'underneath leg sway' is the subsidiary indication.
'underneath' says to put letters next to each other.
'leg' becomes 'on' (cricket term, fielding positions).
'sway' becomes 'hold' (both can mean influence or power).
'on' put next to 'hold' is 'onhold'.
(Other definitions for on hold that I've seen before include "Delayed -- postponed", "Waiting to be connected", "Made to wait (on phone)", "In abeyance", "Pending", "waiting for connection", "Waiting for connection (telephone)", "Postoned, or awaiting reply to phone call", "Left pending" and "waiting for reply".)
