Correct spelling


Correct spelling, explanation: the core word for the correct spelling is commit (which means to carry out or to engage) to which we added noun suffix -ment. This suffix means a state of something, process or a goal of an action. The verb commit has got one t so the form committment is incorrect.

Definition of commitment:
1. noun, obligation or promise to do something

His commitment to that relationship was huge.
The Prime Minister made a commitment to help small businesses’ owners.
2. noun, an act of doing something
