[Forum Game] Change One Letter!

Let's play Change One Letter! The rules are simple:
- Look at the 4-letter word in the post above yours.
- Change exactly ONE letter to make a new English word.
- You cannot add or remove letters (it must stay exactly 4 letters long!).
Example:
Person 1: COLD
Person 2: CORD
Person 3: CARD
Person 4: CART
Our starting word is: CUPS
Let's see how far we can evolve this word! 😝

Curious about the rules and I didn't see it clarified anywhere (if I missed it somewhere very sorry.)
Can you use your one letter change to instead add a letter?
Example: POLL -> POLLS
Example: WERE -> WHERE
Also if you can add a letter can you remove a letter?
Example: HAIR -> (H)AIR
Example: LETTERS -> LETTER(S)
Would there be a limit on maximum and minimum letters or just as long as it's a real English word you are good?

It can't be more than four words, always only changing one letter 🥰
