If I understand correctly, you want to delete all strings in the array
that are of length 1?
If so you can use delete_if
(http://ruby-doc.org/core-1.9.2/Array.html#method-i-delete_if):

1.9.2p290 :001 > a= ["aa", "bb", "cc", "d", "e"]
 => ["aa", "bb", "cc", "d", "e"]
1.9.2p290 :002 > a.delete_if {|word| word.length == 1}
 => ["aa", "bb", "cc"]
1.9.2p290 :003 > a
 => ["aa", "bb", "cc"]
