Oh, yes of course: much better!  And we can get rid of all those
brackets and a bit more:

irb(main):001:0> a =3D "the quick brown fox jumps over the lazy dog"
=3D> "the quick brown fox jumps over the lazy dog"
irb(main):002:0> a.gsub /(\w\W*\w\W*)\w/, '\\1'
=3D> "th quck ron fx jmp ovr te lzy og"

Kind regards
