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

'nationals' is the definition.
Although both the answer and definition are plural nouns, I cannot see how they can define each other.

'entertained by particular gent in eswatini' is the wordplay.
'entertained by' says the answer is hidden in the clue (the clue hosts or entertains the answer).
'ARGENTINES' is hidden within 'particular gent in eswatini'.
