The grammar symbols, made entirely of wood, are part of the study and analysis of the parts of speech. The purpose of these symbols is to make the grammatical function of words visually concrete, so as to help and enhance abstraction in the child. By making them sensorially visible and manually usable, they realise those grammatical abstractions that are attributed to words, but which, as mental orders, are outside them. With the symbol one can give the child not an "adjective" so that he understands it, but "the adjective" so that he can attribute this grammatical function to the words that have the task of acquiring it in language. The use of materialised abstractions, in grammar, extends to all parts of speech, in fact each of them has its own symbol.
