shard

Shard dates back to Old English (where it was spelled sceard) and is related to Old English scieran, meaning "to cut." English speakers have adopted the modernized shard spelling for most uses, but archaeologists prefer to spell the word sherd when referring to the ancient fragments of pottery (sometimes referred to specifically as potsherds) they unearth. While shard initially referred to exactly such items, today the word is also used more broadly to encompass slivers of intangible concepts. A baseless accusation may be made "without a shard of evidence," and fans of the losing team may "cling to a shard of hope" until the final score. The utility of shard is its, ahem, point.
