In Portuguese (Brazil) Inferno means Hell, but I have seen this word in another context, like in games… but I think it does not have the same definition. Is Inferno the same as Hell?
Infernus (Latin) meant underground, of the lower regions, from inferus/infra, meaning below (as in inferior/infrastructure*.)
Inferno is Italian, from Late Latin infernalis "of the lower regions," so originally it referred to the underworld. Since Catholicism emphasized the fiery nature of Hell, inferno came to mean hell, and this use was immortalized by Dante Alighieri in his famous poem The Divine Comedy (written 1308 -1320) (part I: Inferno).
Modern usage of inferno is to connote a particularly hot or dangerous fire, or a place of great human suffering (the final circle of hell is a frozen lake):
of or pertaining to or characteristic of a very uncontrolled and intense fire; a place or condition suggestive of hell, especially with respect to human suffering or death; a place or region that resembles hell, esp. in intense heat. -TFD
"The fire on Thursday afternoon began with an explosion at 121 Second Avenue and grew to an inferno engulfing four neighboring buildings." - NYT
