[Middle English sone, from Old English sōna, immediately, soon.]

Usage Note: In the phrase no sooner, the word sooner is a comparative adverb, just as the word better is in the phrase no better. As such, the expression should be followed by than, not when: No sooner had she opened her book than the doorbell rang. I had no sooner left than she called.
