The Commens Dictionary
Quote from ‘Letters to Mario Calderoni’
A sign in itself may be an indefinite possibility, when I term as a Qualisign, or it may be an existent thing or event, when I term it a Sinsign (sin- is the sim- of simul, simplex, etc.), or it may be a general type, when I call it a Legisign.
