In order to remove not only English words, you should use \p{L}

'Comment ça va ?'.gsub(/\b\p{L}{1,2}\b/, '').squeeze(' ').strip
=> "Coment ?"

i came independently to the same solution as the best answer, so here is a solution considering punctuation

string = 'one a day. One 1, 22  333 0. This days o! o'
p string.split(' ').reject{ |e| i = e.dup; i.gsub!(/\W/, ''); i.length == 1}.join(' ')

#==> "one day. One 22 333 This days"

"once a day".gsub(/\b\w\b/, "").gsub(/\s+/, "")
# => "once day"

This will get rid of 2 or 1 letter words and clean up white space.

str.gsub(/\b\w{1,2}\b/,"").gsub(/\s{2,}/," ").strip

Same thing with an array of values.

str = ["Dave is a dork", "a John is a name", "Shawn is a or Lindsey", "Shawn or Dave"]

str.map! { |str| str.gsub(/\b\w{1,2}\b/,"").gsub(/\s{2,}/," ").strip}

Break your string into individual words, filter out short ones, and then glue the string back together.

puts 'one a day'.split(' ').select{|w| w.length >= 2}.join(' ')
# => one day

Here's how you do it:

string = "on a boat"
result = string.split(' ').reject{|w| w.length < 2 }.join(' ')   # => on boat
