bash shell script help

I need to list every string in a text file and generate the md5 hash for that string next to it on the same line.

I can turn all strings into its md5 hash value but I'm not sure how to list the original string next to it.

I've got

file="/dictionary.txt"

while read line
do
echo $line | md5sum | awk '{print $1}'
done < dicitonary.txt
