# Syntactic rules Syntactic rules of the KVIrc scripting language
In the following table you can find a good part of the KVIrc scripting language syntactic rules. <entity> indicates a ENTITY THAT CAN APPEAR EXACTLY ONE TIME. [<entity>] indicates an OPTIONAL ENTITY. {<entity>} indicates an ENTITY THAT CAN APPEAR ONE OR MORE TIMES. 'entity' indicates a LITERAL ENTITY: written exactly as it is. <entity1>|<entity2> indicates mutually exclusive choices. The mutually exclusive choices are often separated in two or more rules (productions), to improve readability.
