IPA: /spæzˈmɒdɪk/
KK: /spæzˈmɒdɪk/
Describing something that occurs suddenly and irregularly, often in bursts or fits, like a spasm.
The patient experienced spasmodic movements that were difficult to control.
Spasmodic → It is formed from "spasmos" (Greek, meaning a sudden involuntary contraction) and the suffix "-ic" (meaning pertaining to). The word "spasmodic" refers to something that is related to or characterized by sudden, irregular contractions or spasms.
Think of sudden 'contractions' ('spasmos') that happen 'pertaining to' ('-ic') a muscle or movement — that's why spasmodic describes something that occurs in sudden bursts.
