noun
A strong physical or emotional trembling, often from fear, cold, or intense excitement. Literary and somewhat dramatic; in everyday speech 震え (ふるえ) is more common.
恐怖で全身におののきが走った。
A shudder ran through my whole body from fear.
その知らせを聞いて、彼はおののきを隠せなかった。
Hearing the news, he couldn't hide his trembling.
震え is the common, everyday word for shivering or trembling. おののき is more literary and often implies a deeper emotional or fearful shudder.
Derived from the verb おののく (to tremble, shudder). The exact origin of おののく is uncertain, but it is a native Japanese word.
