Affinity is a unique stat first appearing in Fire Emblem: The Binding Blade and reappearing in all subsequent games until Fire Emblem: Shadow Dragon, in which it was removed along with most of the support system, which was the primary usage for Affinity. Despite the return of the support system in the next game, Fire Emblem: New Mystery of the Emblem, Affinity remains absent. Unlike other stats, it cannot be changed, and it only affects combat ability when special support conversations are activated or when the unit's affinity matches that of the level. The stat bonus mechanics for support conversations are as follows:
To calculate the affinity given by each support level, add the two stat boosts together given per affinity, then round down to the nearest whole number. Example: To calculate the damage boost given by an A support with Guy (Fire affinity) and Karel (Light affinity), add the two bonuses given... 1.5 + 1.5 = 3. The evasion bonus given by that support would be 7.5% + 0.0% = 7%, because decimals are rounded down.
In Fire Emblem: Radiant Dawn, different chapter maps were given an affinity. Any character on the map that held an affinity that matched the map's was given a slight advantage in combat. In addition, a player controlled unit with a map-matching affinity had a better likelihood of finding hidden items as opposed to units that did not. Chapter bosses usually held a map affinity.

In Fire Emblem: The Blazing Blade, at the onset of a new file you must enter Tactician data, including a birth month that determines which of the game's 7 affinities your Tactician character will have (in the Japanese version, blood type is also selectable and affects the affinity).
