Putting answer in crossword, after using pen in the beginning, results in difficulty (6)
I believe the answer is:
plight
'difficulty' is the definition.
(plight is a kind of difficulty)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for plight that I've seen before include "State" , "Pledge; predicament" , "Promise - trouble" , "Unfortunate position" , "Jam" .)
