Thoughts are independant of words...our internal views tend to automaticaly be transcribed into language to make it easier to understand and communicate to others of the species.

Dreams are an example of thought untranslated as they don't need to be when asleep and no communication is possible, they lack the guidence of outside stimuli and without a logical narrative thier progression is chaotic.

In studies of chimps a banana was hung from a cieling in a room filled with boxes...without words the chimps still were able to stack the boxes in order to reach the banana. This shows thought and a logical process without words.
