in readiness

1. Available for use or action at any time. My sister could go into labor any day now, so I am in constant readiness. The volunteers descended on the garden, their shovels in readiness upon further instruction. I always have a frozen casserole in readiness for dinner on chaotic days like this.

2. In anticipation of or in preparation for (something). I did some research in readiness of the lecture, so I can ask some good, probing questions on behalf of the newspaper. Hey, can you gather supplies in readiness for tomorrow's art project? You need to do the reading every night in readiness of a pop quiz—Ms. Miller gives them all the time.
