reignites

Reignite is a verb that means to light again after the flame has been extinguished, or more broadly, to revive or renew a feeling, interest, debate, or situation that has faded. The word combines the prefix re-, meaning again, with ignite, which traces to Latin ignis, fire, and related forms. In common use, reignite can describe both literal combustion and figurative revival.

In everyday language, reignite is used for restoring a fire or flame, such as reigniting a campfire or reigniting a candle. It is also used metaphorically to describe reviving interest or enthusiasm, for example, reigniting public interest in a topic, reigniting a political debate, or reigniting a romantic relationship (though rekindle is a common alternative).

In technical contexts, reignition refers to restarting a flame or plasma after it has been extinguished, such as in combustion engineering, rocket propulsion, or industrial burners. The noun reignition is used similarly, as in the reignition of a flame or the reignition of a process after a shutdown.

Synonyms include rekindle, revive, ignite again. The choice among them can convey slightly different nuances: rekindle often emphasizes warmth or affection, while reignite stresses the act of lighting again, either literally or figuratively.
