Shiver
noun /ˈʃɪvə/ — A group of sharks — a name that performs its own meaning.
Definition
The collective noun for a group of sharks — remarkable for the way it captures, in a single word, the physical sensation that the sight of a shark produces. One of the most precisely onomatopoetic collective nouns in the language.
Beyond the definition
Someone looked at a group of sharks and asked: what do they make you do? And then they used that answer as the name. A shiver of sharks. The collective noun as emotional truth.
Origin & history
English collective noun tradition. The genius of this particular choice lies in its double meaning: sharks travel in shivers; the sight of them produces one. The word earns both.
