What is the difference between huge and enormous and vast and immense and prematurely and early and untimely ?Feel free to just provide example sentences.

“Huge” and “enormous” are the same. Both mean that whatever it is is very, very, large. You may have a “huge” or “enormous” ship, horse, car, ocean, elephant, hair brush, or meal. Both words can be used on pretty much anything you would like to say is more than just “big”.

“Vast” usually has to do with space. You might have a “vast” ocean or “vast” sky, but not a “vast” car or building.

“Prematurely” means before its time, when it should not be. A baby born “prematurely” is a baby born before the due date. If you speak “prematurely”, you spoke too soon.

“Early” just means before the time, but not necessarily in a bad way like prematurely. You might arrive at work “early”. You might wake up or go to bed “early”. You could also say a premature baby is born “early”. There isn’t a positive or negative meaning for “early”.

“Untimely” means whatever it is should not have happened then. An “untimely” death is a death that was particularly badly timed. Arriving to class in an “untimely” manner probably means you are late. It’s a negative word, not neutral like “early”.
