Here are the reasons why most flags don't use words:
* Simplicity and Recognition: Flags are meant to be easily recognizable from a distance, even when waving in the wind. Words can be too small and detailed to be seen clearly, especially on a moving flag.
* International Understanding: Flags are a universal form of communication, and using words would limit their understanding to those who speak the language.
* Symbolic Representation: Flags often use colors, shapes, and patterns to represent specific historical events, cultural elements, or values, which can be more powerful and evocative than words.
Examples of Flags with Words:
* Saudi Arabia: The flag features an inscription of the Islamic shahada ("There is no god but God, and Muhammad is the Messenger of God") in Arabic script.
* Cambodia: The flag features a white inscription of "National Flag of Cambodia" in Khmer script.
* Nepal: The flag features a stylized depiction of the sun and moon with the Nepali script for "Nepal" written within the moon.
It's important to note that even these flags primarily use symbolism, with the words being a small part of the overall design.
Overall, the use of words on flags is a rare exception. Most flags rely on visual elements to communicate their meaning effectively.
