I believe the answer is:

leonard

I'm a little stuck... Click here to teach me more about this clue!

'was he nimoy' is the definition.
The definition suggests a singular noun which matches the answer.

'or alden seen sloshed?' is the wordplay.
'or alden' can be anagrammed to 'LEONARD'.
Though, I am not sure how this is indicated.

Can you help me to learn more?
