Yeah, it’s spelled “addicting”, you’re right

No, "addicting" is not the correct spelling. The correct spelling is "addictive." If you're not sure about the spelling of a word, there are a few ways you can check:

1. Use a Dictionary: Look up the word in a dictionary. Online dictionaries like Merriam-Webster, Oxford English Dictionary, or Dictionary.com can provide the correct spelling as well as the definition and usage of the word.
2. Use a Spell Checker: If you're typing on a computer, you can use the spell checker feature in your word processing software or browser. Most spell checkers will underline or suggest alternatives for misspelled words.
3. Search Engine: If you're unsure about a spelling, you can try doing a quick search on a search engine like Google. Type the word as you think it is spelled and see if it autocorrects or shows you the correct version.

Remember, it's always best to double-check the spelling of a word to ensure accuracy in your writing.
