Part of a ship sometimes replaced (3)
I believe the answer is:
hip
'replaced' is the definition.
The answer and definition are not the same part of speech. However, adjectives and past participle verbs can occasionally mean the same thing.
'part of a ship sometimes' is the wordplay.
'part of' indicates the answer is hidden within the clue.
'HIP' is hidden in the letters of 'ship sometimes'.
Can you help me to learn more?
(Other definitions for hip that I've seen before include "flask here?" , "Leg joint" , "it can nowadays be replaced" , "Trendy or stylish, like fruit of the wild rose" , "Rose fruit; start of cheer" .)
