There are words that don't qualify for our words. Here's a list of types of words that we excluded from our vocabulary:

- Two-letter words (to, at, on, etc.)
- Abbreviations (IRS, NYPD, etc.)
- Prefixes and Suffixes (pre-, -er, etc.)
- Offensive words, slurs, etc.

If you see a word that fits our guidelines, yet you can't enter it - contact us and tell us about it.
