Largely wet and fertile, suitable for sporting? (8)

'suitable for sporting?' is the definition.
I can't judge whether this definition defines the answer.

'largely wet and fertile' is the wordplay.
'largely' means to remove the last letter (most but not all of the letters).
'and' says to put letters next to each other.
'fertile' becomes 'arable' (I've seen this before).
'wet' with its last letter taken away is 'we'.
'we'+'arable'='WEARABLE'

Can you help me to learn more?
