You can also sell in the money call options in anticipation the stock will go down. You keep the premium the call buyer pays.

But to sell the calls, you should own the stock first. Puts can be bought w/o owning the stock. Granted, the put buyer pays the premium, so you don’t get guaranteed money in your pocket like you would selling calls.

I think you're referring to covered calls, but you can sell naked calls as well, meaning without owning the underlying.

You’re right, but the keyword in my post was “should”. If you have to look up “short selling” in the dictionary (as in OP’s case), naked options aren’t on the menu.
