LoCoS

LoCoS (short for Lovers Communication System) is a pictorial language developed by Yukio Ota of Japan in 1964. It was meant as communication for the deaf and mute as well as for the illiterate. It is a universal and simple language, and as Ota put it, "It should emphasize the importance of communication among all the people of all the countries of the world."

Symbols
There are 8 major symbols in LoCoS. There is the Sun or day, represented by a circle. There is man, represented by a ring shape. There is a thing, represented by a square. There is thought, represented by a triangle with a slightly cut off top. There is feeling, represented by a heart. There is land or place, represented by a low straight line. There is the question indicator, a question mark. There is, lastly, a point or existence, represented by a single point.

Words
Words are made by combining different symbols in different ways. For example if you put a dot inside a circle it will represent today, or if you put a fish in a ring shape it will be a fisherman. There are around 80 words that are official according to Yukio Ota. Words can be created as long as they follow the basic word syntax.

Sentences

The middle row is used for the core words (nouns, verbs, and direct/indirect objects). The top row is used to modify verbs with adverbs. The bottom row is used to modify nouns using adjectives.
