Heavy rope could be transported in rickshaw, servant observed (6)
I believe the answer is:
hawser
'heavy rope' is the definition.
(I've seen this before)
'in rickshaw servant observed' is the wordplay.
'in' indicates the answer is hidden within the clue.
'HAWSER' is hidden within 'rickshaw servant observed'.
'could be transported' is the link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for hawser that I've seen before include "A strong rope, maybe of steel" , "Ship's large rope or small cable" , "Nautical rope or cable" , "tower" , "Heavy rope for nautical use" .)
