IPA: /ˈmʌltɪplɛt/
KK: /ˈmʌl.tɪ.plɛt/
A group of related particles or spectral lines that have similar properties but may differ in certain characteristics, such as electric charge or energy states.
The physicist studied the multiplet to understand the behavior of the particles involved.
Multiplet → It is formed from "multi-" (meaning many) and "-plet" (from Latin "plectere", meaning to fold or intertwine). The word "multiplet" refers to a group or set of multiple related items or entities, often used in scientific contexts to describe a set of closely spaced energy levels or spectral lines.
Think of 'many' ('multi-') things that are 'folded together' ('-plet') — that's why a multiplet refers to a group of related items.
