Why this word is great
EXIGENT — [Adjective] Pressing; requiring immediate action or remedy, especially in a manner that makes rigorous or critical demands. From Latin exigēns, present participle of exigō (“to demand, require, drive out”), from ex- (“out”) + agere (“to drive”). Unlike “urgent,” which suggests general haste, or “imperative,” which speaks of absolute command, “exigent” denotes the specific pressure of a circumstance that actively compels and consumes, demanding resources under relentless external duress. It is the cold glare of a low-fuel warning light on a deserted highway, the precise, gathering frequency of a distant siren, or the metronomic beep of a hospital monitor whose rhythm has suddenly changed. Necessity, in this form, is not a request but an expulsion from comfort—the moment when circumstance itself becomes a ruthless creditor.
