Still working on that NaNoWriMo novel? Whether you’re trying to churn out a 50,000-word novel or just sticking to short stories for now, impeccable writing skills are key to success in the long run, and that includes proper grammar and spelling of everything from simple words to long phrases and idioms. There are plenty of everyday expressions that we’re used to hearing but not reading or writing, and this often leads to misspellings. It never hurts to keep notes of these misheard idioms for future reference, which is why I compiled another list of words and phrases from the Elevate – Brain Training app, this time from the Expression game.

So continuing on a trend of writing lessons from Elevate, here are 14 common expressions that you may be writing incorrectly. Enjoy!

1) All of a sudden: an alternative expression for “suddenly”. Write “all of a sudden”, not “all of the sudden”.

2) Compliments of the house: indicates that something is being given for free. Write “compliments of the house”, not “complements of the house”.

3) Couldn’t care less: expresses a complete lack of interest. Write “couldn’t care less”, not “could care less”.

4) Deep-seated: describes something firmly established at a profound level. Write “deep-seated”, not “deep-seeded”.

5) Due diligence: the reasonable steps taken to satisfy a legal requirement. Write “due diligence”, not “do diligence”.

6) En route: a French expression meaning “during the course of” or “on the way”. Write “en route”, not “on route”.
