Faldage,

Suppose I typed a group of random letters into an otherwise sensible sentence. Would we agree that the random letters were a 'non-word'? I'm suggesting this as a point of departure for the discussion.

Example sentence: Watching the labent water descend from the thawing pipe, the plumber considered eoxlibnsdaienvlab the brevity of life.

Can we agree or not that 'eoxlibnsdaienvlab' is a non-word?
