The verb drop suggests an abrupt descent or downward trajectory. It can be used of items that are falling in a literal sense, such as rain from the sky or acorns from a tree, or of immaterial things—such as prices or temperatures. The synonym plummet suggests an even more rapid and steep descent, as if being pulled down by a weight. There's a reason for the extra weight: the word plummet (noun) originally referred to a piece of lead or some other weight attached to a line, used for determining the perpendicularity or depth of something. So, when prices or temperatures plummet, they decrease sharply and dramatically, as if being pulled down by something heavy.

Roses are red, violets are blue—poets they’re called, but you can call them bards, too. Bard is an old-fashioned synonym for poet. In medieval times, the noun bard referred to a person who composed and recited epic or heroic poems, often while playing the harp, lyre, or the like. Earlier still, the term was also used to refer to one of an ancient Celtic order of composers and reciters of poetry. By the time William Shakespeare was rattling off verses, bard was in circulation as a more general term for a lyric or epic poet—and eventually the term came to be associated with Shakespeare himself, who came to be known variously as the Bard of Avon, or, more definitively, the Bard.

The verb heal is used to talk about freeing people or things from ailments and making them healthy, whole, or sound. The synonym restore is not used in exactly the same way; you might heal from a wound, but you would not restore from a wound. You could, however, restore order, that is, reestablish order or bring it back into existence, or you could restore a painting, that is, bring it back to a former condition. But neither of these uses overlap squarely with heal. Restore is closest to heal when used in the context of bringing a person or thing back to a state of health, soundness, or vigor after suffering damage or depletion: After a grueling week that left her feeling quite exhausted, a long hike in the woods restored her vitality. In the context of ecology, the related noun restoration refers to the act of bringing ecosystems that have been damaged or destroyed back into balance by way of human intervention. The theme for Earth Day 2021 is Restore Our Earth, a call to action that invites everyone to take an active part in bringing the world’s ecosystems back into balance through natural processes, emerging green technologies, and innovative thinking.
