Cathy steered the boat (5)
I believe the answer is:
yacht
'boat' is the definition.
(I know that yacht is a more specific form of the action boat)
'cathy steered' is the wordplay.
'cathy' anagrams to 'YACHT'.
But, I am not clear how this is indicated.
'the' acts as a link.
Can you help me to learn more?
(Other definitions for yacht that I've seen before include "Sailing boat" , "Pleasure craft" , "Luxury purchase" , "Type of boat" , "Light sailing-vessel for sport" .)
