Go with current meaning (5)
I believe the answer is:
drift
I believe this clue is a double definition.
'go with current' is the first definition.
(as in drifting in the water)
'meaning' is the second definition.
(drift is a kind of meaning)
(Other definitions for drift that I've seen before include "Float along as on waves" , "Walk casually; snow pile" , "Movement off course or in general" , "Trend; meaning" , "wander from place to place" .)
