Recently arrived in Spain, Rob went climbing (7)
I believe the answer is:
newborn
'recently arrived' is the definition.
The answer and definition are different parts of speech. However, adjectives and past participle verbs can occasionally mean the same thing.
'in spain rob went climbing' is the wordplay.
'in' indicates a hidden word.
'climbing' shows that the letters should be reversed in order (in a down clue, letters climb up).
'nrobwen' is hidden in the letters of 'spain rob went'.
'nrobwen' written backwards gives 'NEWBORN'.
Can you help me to learn more?
(Other definitions for newborn that I've seen before include "Just entered the world" , "Neonate" , "Recently given birth to" , "Young baby" , "Recently delivered" .)
