The total number of characters (individual graphs) in the largest Chinese dictionaries is a little under 50,000, but less than a fifth of those are found with any regularity in the classical texts, and still today a working vocabulary of from 5000 to 7000 graphs is considered sufficient for all but the most advanced reading. A very small set of these characters are labelled “pictograms”, or “pictographs”, being basically stylized pictures of what they stand for: “tree” is written 木, the sun 日, and child, 子. These characters are highly stylized now. They better represented what they signified before, but were nevertheless conventional even then, as all characters have been (see below).
