If someone asked you if you were planning to pernoctate, would you know what they meant?

This is a word I came across today in the blog A Linguist Abroad in a post about ‘Interesting’ Cambridge rules. It appears in the sentence:

A Tutor (the pernoctating Tutor) is on duty every night and may stop a gathering forthwith if it is causing disturbance to other members of the College or neighbouring community.

(emphasis added)

To pernoctate [ˈpɜː.nɒk.teɪt] (UK) [pɚˈnɑkˌteɪt] (US), is “to stay all night; to pass the night (especially in prayer)”, according to Wikitionary.

A pernoctation is:

– An overnight stay; action (or instance) of abiding through the night at a location.
– The action (or an instance) of walking about at night, especially as a vigil or watch.
– A religious watch kept during normal sleeping hours, during which prayers or other ceremonies are performed.

According to the usage notes, “the sense of a religious watch may apply either to a holy vigil or to diabolical activities.”

These words come from the Late Latin pernoctātiō ‎(a spending [of] the night), from the Latin pernoctāre (to send the night), from per- (through) and nox/noct- (night).

Students who need to work all night to finish an assignment / essay, or to revise for an exam might “pull an all-nighter”.

Are there other ways to express this idea?
