Emily Dickinson Lexicon

LOLL, v.i. [Eth. አለወለወ alolo, to thrust out the tongue. The sense of this word is to throw, to send. Hence it coincides with the Gr. λαλεω, W. lloliaw, to speak, to prate, Dan. laller, G. lallen. It coincides also with lull, to appease, that is, to throw down.]

1. To recline; to lean; properly, to throw one's self down, hence, to lie at ease. Void of care he lolls supine in state. – Dryden.
2. To suffer the tongue to hang extended from the mouth, as an ox or a dog when heated with labor or exertion. The triple porter of the Stygian seat, / With lolling tongue lay fawning at his feet. – Dryden.
