Every now and then – usually when talking with an older individual or someone from the United States Midwest or South – I hear the word "spell" used to mean a short period of time, such as: "Come sit down and rest a spell." I've also heard it used as a verb, like, "When Pete arrives he will spell Tito, who has been working since dawn."
What is the history and origins of this meaning and use of the word spell? And is it a colloquialism or can it be used in more formal settings?
Best Answer
Merriam-Webster gives the origin of this meaning as "probably alteration of Middle English spale substitute, from Old English spala."
The Online Etymology Dictionary says the first recorded use of spell to mean an "indefinite period of time" is in 1706.
Also, M-W does not list this usage of spell as a colloquialism or slang, so I think it's appropriate for formal writing, wherever it is appropriate to use such a vague word.
