The general trend in current travel (5)
I believe the answer is:
drift
I believe this clue is a triple definition!
'the general trend' is the first definition.
'drift' can be an answer for 'trend' (synonyms). I'm unsure of the 'the general' bit.
'in' is a link.
'current' is the second definition.
(can be similar in meaning in navigation contexts)
'travel' is the third definition.
(I know that drift is a more specific form of the action the travel)
Can you help me to learn more?
(Other definitions for drift that I've seen before include "spirit" , "Travel without purpose" , "non-standard deviation?" , "Large heap (of snow)" , "Move with the current" .)
