# How can comma placement change the meaning of a sentence?

Apr 6, 2018

Commas can alter the meaning by modifying the grouping of words.

#### Explanation:

Here is one example:
[1]$\textcolor{w h i t e}{\text{XXX}}$I saw the twins, Alice and Josie.
versus
[2]$\textcolor{w h i t e}{\text{XXX}}$I saw the twins, Alice$\textcolor{red}{,}$ and Josie.

In case [1] I saw two people, namely the twins whose names were Alice and Josie.

In case [2] I saw four people, namely the twins and also Alice and Josie.
