Difficulty
A difficult task is the opposite of an easy task. A difficult task requires effort and is troublesome or hard. Difficult and difficulty are things needing much labour to do - not a small or moderate amount of labour, but much labour.
Example
A fit man would not find climbing stairs difficult even though effort is involved. A man with a heart condition may experience breathlessness or pain or may take a long time to climb the stairs. The man with the heart condition would find the task difficult.
