IPA: /prɪˈmɒnɪtərɪli/
KK: /prɪˈmɒnɪtərɪli/
In a way that warns or indicates something will happen in the future.
She felt a premonitorily sense of dread before the storm arrived.
Premonitorily → It is formed from "pre-" (meaning before) and "monitor" (from Latin "monere", meaning to warn). The suffix "-ly" indicates the manner of the action. Thus, "premonitorily" means in a manner that warns beforehand.
Think of 'pre-' meaning before and 'monitor' meaning to warn — so when something happens 'premonitorily', it is a warning that comes before.
