IPA: /əˈtræktər/
KK: /əˈtræktər/
A person or thing that draws attention or interest, or in physics, a set of properties that a system naturally moves towards.
The bright colors of the flowers make them great attractors for bees and butterflies.
Attractor is formed from "ad-" (meaning to) and "tractus" (meaning drawn or pulled). The word describes something that draws or pulls things towards it.
Think of something that 'draws' ('tractus') things 'to' it ('ad-') — that's why an attractor is something that pulls things in.
