The Commens Dictionary
Quote from ‘P of L’
...a sign which is of the nature of a general type, law, or habit, which I will call a legisign. Thus, the word ‘the’ occurs, on the average, twenty times on an English page (more or fewer times, according to the style), and all these are so many occurrences of one and the same word. In that sense a word is a ‘legisign.’ But a legisign can only exists in such occurrences, which I term its replicas; and each of these replicas is a suisign.
MS [R] 800:2
