Why can't this also be "I know words"? Sometimes the word "les" can either mean nothing or the word "the" but in this case it must be translated to "the"?

By the way, "je sais les mots" does not mean a lot to me. I would use "connaître" here...
"Je connais les mots" make more sense. I just finished savoir vs connaître at French about site. Thanks sitesurf, I really find you a very helpful coach.
what is the difference in pronunciation between the plural and the singular je sais le mot. je sais les mots.
The difference is in the article. "LE" sounds like "Luh" and "LES" sounds like "Lay" singular and plural respectively.
