I believe the answer is:

endure

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

'suffer' is the definition.
(I know that suffer can be written as endure)

'stoically even when duress is applied from outside' is the wordplay.
'ENDURE' is hidden in amongst the letters.
However, I'm uncertain how the hidden word is indicated.

Can you help me to learn more?

(Other definitions for endure that I've seen before include "Stand" , "Stomach" , "Put up with or withstand" , "Undergo hardship patiently" , "Tolerate, put up with" .)

I've seen this clue in The Irish Times.
