1. Spaces: The most common thing that comes between words in a sentence is a space. This helps us visually distinguish one word from the next.
2. Punctuation: There are several types of punctuation that can come between words, including:
* Commas (,)
* Periods (.)
* Question marks (?)
* Exclamation points (!)
* Colons (:)
* Semicolons (;)
* Dashes (-)
* Parentheses ()
3. Other elements: Less commonly, other things can come between words, such as:
* Apostrophes (') for contractions or possessives
* Quotation marks ("") for direct speech or titles
* Hyphens (-) for compound words or to join words together
