Take care of U-turn when travelling about (7)
I believe the answer is:
nurture
'take care of' is the definition.
(I've seen this in another clue)
'u-turn when travelling about' is the wordplay.
'when travelling' indicates anagramming the letters.
'about' becomes 're' ('re' means regarding or about).
'u'+'turn'='uturn'
'uturn' anagrammed gives 'nurtu'.
'nurtu'+'re'='NURTURE'
(Other definitions for nurture that I've seen before include "Cultivate" , "Cherish (an ambition)" , "Supply sustenance to" , "Encourage development of (a child)" , "Sustain" .)
