echo $(grep "^[^']\{3,5\}$" /usr/share/dict/words|shuf -n4)
The improvement of this command over Strawp's original alternative is that you can specify the size of the words, in this particular case words between 3 and 5 character's long. It also excludes words that contain apostrophes, if you'd rather keep those words simply substitue [^'] for .

echo $(grep "^[^']\{3,5\}$" /usr/share/dict/words|shuf -n4) Useless use of 'echo'

RanyAlberg, actually it's there on purpose. It serves the purpose of displaying the words on the same line. Just like |tr -d '\n' only slightly better since it adds a newline at the end.

It's slow as hell on my french dictionary (139719 words in it). Faster with : echo $(shuf -n4 /usr/share/dict/words)
