==== Flavoured mesons ====
Flavoured mesons are mesons made of pair of quark and antiquarks of different flavours. The rules are simpler in this case: The main symbol depends on the heavier quark, the superscript depends on the charge, and the subscript (if any) depends on the lighter quark. In table form, they are:<ref name=PDGMesonsymbols/>

;In addition:
* If [[Total angular momentum|{{mvar|J}}]]<sup>[[Parity (physics)|P]]</sup> is in the "normal series" (i.e., [[Total angular momentum|{{mvar|J}}]]<sup>[[Parity (physics)|P]]</sup> = 0<sup>+</sup>, 1<sup>−</sup>, 2<sup>+</sup>, 3<sup>−</sup>, ...), a superscript ∗ is added.
* If the meson is not pseudoscalar ([[Total angular momentum|{{mvar|J}}]]<sup>[[Parity (physics)|P]]</sup> = 0<sup>−</sup>) or vector ([[Total angular momentum|{{mvar|J}}]]<sup>[[Parity (physics)|P]]</sup> = 1<sup>−</sup>), {{mvar|J}} is added as a subscript.
* When the [[Meson spectroscopy|spectroscopic state]] of the meson is known, it is added in parentheses.
* When the spectroscopic state is unknown, mass (in [[Electronvolt#Mass|MeV/''c''<sup>2</sup>]]) is added in parentheses.
* When the meson is in its [[ground state]], nothing is added in parentheses.
