How to delete certain words from a word cloud in mathematica?

I generated word clouds from a text file in Mathematica. I was able to remove words with 5 or less characters from the cloud.

 fdp2 = StringReplace[fdp, 

 WordBoundary ~~ Repeated[WordCharacter, 5] ~~ WordBoundary -> ""]
 WordCloud[fdp2]

But there are still useless words in the cloud. How can I remove a specific word like "become" from a word cloud?
