The design and description of flags typically uses specialized flag terminology with precise and technical meanings (a form of jargon).
Flag illustrations generally depict flags flying from the observer's point of view from left to right, the view known as the obverse; the other side is the reverse. Animals and beasts should always appear with the heads facing the flag-staff side.
Some countries use a single flag design as a national flag for all purposes. Other countries may use two or more flags for different purposes but all serving as the national flags. Vexillologists categorise such flags as:
Civil Ensign - Flown on private vessels (fishing craft, cruise ships, yachts, etc).\n* State Ensign - Flown on unarmed government vessels.\n* War Ensign - Flown on warships.\n* Civil Flag - Flown by citizens on land.\n* State Flag - Flown on public buildings.\n* War Flag - Flown on military buildings.
