Carry a piece of tube around (4)
I believe the answer is:
bear
'carry' is the definition.
(bear can mean to transport or carry)
'a piece of tube around' is the wordplay.
'a piece of' says the answer is hidden in the clue.
'BEAR' is hidden within 'tube around'.
(Other definitions for bear that I've seen before include "Large carnivore" , "Carry - teddy" , "eg Paddington or Yogi" , "Beast - tolerate" , "Carry; large animal" .)
