Signs are an important part of modern life. We can see them everywhere, on roads, in stations, at airports and even in schools.
Signs have a grammar. We use triangular signs to give warnings. We use circular signs to give orders and finally we use rectangular signs to give information.
In many cases try not to use words. This helps people who speak a different language or people who can’t read.
When you design a new sign you need to make sure that people understand the right message. For example, some conservationist in India wanted to protect the tiger. They decided to make some signs. They wanted to make people think before killing tigers. Many villagers could not read so they did not use any words. In the end, they made a sign of a tiger’s head with a X through it. Unfortunately, the villagers understood this as an instruction to kill tigers!
