Chasten and chastise

Well, my brain is wired a little oddly (yeah, fine, all right, ‘little’ may be contextually dubious…), so it woke me up at around 0500 this morning with the announcement “Hey!! I betcha ‘chasten’ and ‘chastise’ have something to do with religious purity standards, y’all should look that shit up!!”… so here I am at lunchtime finding out that my brain was worryingly spot on, and doing an etymology excavation.

So, chasten and chastise both mean (today) something close to punish, or reprimand. You’ll also find the related word ‘castigate’ in use. None of the three is very common in today’s English, but you’ve probably heard or seen at least one of them – e.g. ‘Chastened, the princess lowered her shining head.’ You’ve probably also heard of ‘chaste’ and ‘chastity’.

If chasten and castigate instead bring up images of leather, spikes, and a dominant with a whip, well, I’m not here to judge, although that thought brings us neatly into the actual etymology of the word.

Depending on where you look, chasten showed up in either the 13th century or the 16th, and comes from the Old French ‘chastiier’ or ‘chastier’, which meant to punish, to dominate, to instruct.

That verb in turn appears to have a Latin root, coming from castigare, ‘castigate’ or castus, ‘morally pure, chaste’.

So, from ‘castus’, we find ourselves in need of a way to enforce a state of castus, and end up with ‘castigare’, which is a form of punishment, frequently physical.

This concept of physical or other punishment to enforce moral standards is a popular enough concept to survive down the centuries to show up today in the form of chasten and castigate. The Inquisition is a particularly well-known historical example of the abstract.

Frankly I think the BDSM take is mentally healthier, but there you are, gentlebeings: chastise and chasten, excavated.

What is etymology, and why are you excavating it?

Etymology is like the archeology of a language (definition: the study of the origin of words and the way in which their meanings have changed throughout history).
