I believe the answer is:

san marinese

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

'landlocked people being' is the definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.

'sensible keeping naval forces?' is the wordplay.
'sensible' becomes 'sane' (sane can mean sensible or reasonable).
'keeping' indicates putting letters inside.
'naval forces?' becomes 'marines' (I've seen this before. I am not sure about the 'naval' bit.).
'sane' enclosing 'marines' is 'SAN MARINESE'.

Can you help me to learn more?
