Dictionary.com removes binary-gendered phrases

Dictionary.com has also announced the decision to remove binary-gendered phrases like "his or her" and "he or she," which had appeared in hundreds of entries.

"This change was made for two reasons: inclusivity and usage," said Dictionary.com in their statement.

“Updating binary-gendered phrases makes the entries more similar to how people actually speak and write. The entries are now more natural sounding," said Barrett.

Dictionary.com said that it "aspires to empower every person, of every background to express themselves, make connections and open the door to opportunity through the power and joy of language".

How does Dictionary.com add words?

Dictionary.com says it doesn't make up words – words are added "because they’re real – because they’re really used by real people in the real world."

"We can’t endorse any word, but we can document their use in the real world. We are descriptive—we describe language as it is really used (not just how we or others may wish it would be used)," said Dictionary.com.

Dictionary.com uses the following criteria to determine whether a word should be added:

1. It’s a word that’s used by a lot of people.
2. It’s used by those people in largely the same way.
3. It’s likely to stick around.
4. It’s useful for a general audience.
