Correct spelling


Correct spelling, explanation: when a word ends with silent e this vowel disappears after adding the suffix -ing. This way, adding -ing to the verb use the correct spelling is using, not useing.

Definition of using:
1. verb (gerund form), to carry out a purpose, to make use of
You shouldn’t be using your phone while driving!
2. noun, exercising sth, putting sth into action
Using this shampoo really made my hair stronger.

Incorrect spelling


Incorrect spelling, explanation: this spelling is incorrect due to the rule which says, that when making a gerund form we drop the silent e from the end of a word. Therefore useing is incorrect and the correct spelling is using – the last vowel isn’t pronounced so it disappears after adding the suffix.
