Correct spelling


Correct spelling, explanation: the word has its origins in the verb come (to move, travel, get somewhere) and the suffix -ing used to create an adjective or noun out of a verb. When we add an i to a word ending with e we omit the e in the spelling, therefore come + -ing is coming.

Definition of coming:
1. adjective, happening very soon
Party coming this Saturday is going to be amazing!
2. noun, arrival
Coming here was not a good idea.
