Words are thoughts but thoughts are not necessarily words. I do think words form better thoughts. Without words, thoughts are memories and can shift and change meaning and I won't be aware of it. If I think my thoughts in words then I can review my thoughts more carefully and be sure the meanings are not changing. If I'm solving some complicated problem, this is a big deal since if my solution to a sub-problem changes that's very bad. Of course also I can then write my thoughts down and refer back to them repeatedly so I can be sure they remain consistent.
