On the street, always give guidance (5)
I believe the answer is:
steer
'give guidance' is the definition.
(I've seen this before)
'on the street always' is the wordplay.
'on' says to put letters next to each other.
'the street' becomes 'st'.
'always' becomes 'eer' (poetic way of saying ever).
'st' put next to 'eer' is 'STEER'.
(Other definitions for steer that I've seen before include "Reset so as to direct" , "Guide (a ship, car, etc)" , "Direct; young ox" , "Drive - young ox" , "Navigate" .)
