Unsatisfied vs Dissatisfied:
If you are unsatisfied with something, you are disappointed because you have not got what you hoped to get.
If you are dissatisfied with something, you are not contented or pleased with it.
Both words express a lack of satisfaction, “unsatisfied” is a more neutral term while “dissatisfied” has a stronger negative connotation.
Mnemonic:
‘un’ = 2 letters
‘dis’ = 3 letters (1 letter more, so stronger in negative emotion)
