IPA: /ˈɛm.ə.neɪ.tər/
KK: /ˈɛmənˌeɪtər/
A person or thing that produces or sends out something, such as light, energy, or ideas.
The sun is an important emanator of light and warmth for our planet.
Emanator → It is formed from "emanare" (from Latin, meaning to flow out) and the suffix "-tor" (meaning one who). An emanator is one who flows out or gives off something, such as light or energy.
Think of something that 'flows out' ('emanare') — that's why an emanator is something that gives off or radiates.
