This article attends to “questionnaires” in linguistic fieldwork defined by the inclusion of sensory stimuli. It shows that such non-verbal protocols have been used to help elucidate and compare semantic content, which has generally been subordinated to formal analysis in the history of linguistics. To explain and exemplify this relationship, I target the color questionnaire developed by Hugo Magnus, which included ten standardized color chips and a long list of interview questions on language use. Magnus’s questionnaire (Fragebogen) decoupled perception and (...) denotation in its day, though similar protocols have recently been employed to restore the connection between meaning and form.
