use a word as a delimiter with cut

Is there a way to use a word as a delimiter with cut? Or is there a way to use sed or awk with a word as a delimiter? I don't care which program I use for a delimiter I just want to use a word as a delimiter.

You can use anything as a delimeter...

 
echo "onewordtwowordthreewordfour" | awk -F"word" '{print $1}'
$ echo "onewordtwowordthreewordfour" | ruby -F"word" -ane  'puts $F'
one
two
three
four
