Synonym discussion
Sense: noun/1
Readiness is the broadest of these four, covering both being prepared and being willing. Preparedness focuses narrowly on training, supplies, and logistics — you hear it in military or disaster planning contexts. Willingness is only about consent or attitude, with no implication of being equipped or trained. Eagerness adds enthusiasm and a strong desire to begin, making it warmer and more personal. Alacrity is a more formal word that suggests cheerful, brisk willingness — it appears in writing more than speech. A commander might praise a unit's readiness and preparedness, while a manager might thank an employee for their willingness or eagerness to take on extra work.

Etymology
Readiness comes from the adjective ready (from Old English ræde, meaning 'prepared, prompt') combined with the noun-forming suffix -ness, which turns adjectives into nouns describing a state or quality. The word has been used since the Middle English period.
