The educational challenge of polysemy of words used both in non-formal (every-day) and scientific formal languages is addressed. An analysing tool; the triadic approach; has been elaborated to make this kind of polysemy of words explicit by discerning three different sets of meaning: non-formal; a scientific quality and a physical quantity; respectively. The discernment process is a particular way of seeing the critical aspects of variation of meaning simultaneously connected to one and the same invariant word (symbol).
