Bad: prepitional
Good: prepositional

Here is a way to remember the spelling of this word. Often the reasons authors try to cut down on prepositional phrases is because they can make a sentence wordy. Often prepositional phrases are unnecessarily. Because of their position in a sentence, I can remember prePOSITIONal phrase.

Have a better idea to remember this word? Please share it in the comment section of this blog. Thanks.
