IPA: /ˌstrɪdʒ.əˈleɪ.ʃən/
KK: /strɪdʒʊˈleɪʃən/
A high-pitched sound made by some insects, like crickets and grasshoppers, when they rub parts of their bodies together.
The stridulation of the crickets filled the night air with a soothing melody.
Stridulation → It is formed from "stridere" (meaning to creak or chirp) and the suffix "-ation" (indicating a process or action). The word describes the process of producing a creaking or chirping sound, often associated with insects.
Think of the sound of insects 'chirping' ('stridere') as part of the action or process ('-ation') of making that sound.
