  • "But the tight in sleep tight, meaning 'sleep soundly,' almost certainly comes from the use of tight and tightly to mean 'soundly, securely, properly,' a use that dates back to Shakespeare. The phrase sleep tight also first appeared in the mid-19th century, a bit after such beds were popular, and from the first was most commonly heard in variations on the classic rhyming bedtime salutation 'Good night, sleep tight, and don’t let the bedbugs bite.' The impulse of tour guides to tie the phrase sleep tight to beds sporting ropes that had to be kept tight must be nearly irresistible, but I’m afraid that doesn’t make it true."
