I don’t speak French, so this looks like it might translate to ‘The Cat-Maker’. But ‘cat’, in French, is ‘chat’ and not ‘chât’ isn’t it? Maybe the name is related to ‘château’? Maybe ‘Castle-Maker’?

My paper-back dictionary says “cat’s hole - as in a door, etc.”

Are you sure it is not a name?

It’s a place-name. I’d wager it has an etymological connection to château rather than a chat.

It’s a person’s name (in the most famous case) - the principle is named after [this guy](http://en.wikipedia.org/wiki/Henry_Louis_Le_Chatelier), who discovered it.

Yes, it’s a name. But names have a meaning. For example, Messerschmidt is Cutler and Schumacher is Shoemaker and du Bois is ‘of the woods’ for Wood or Woods.

Typically the carat “^” replaces an “S”, as in hospital or hostel, so your second guess would most likely be right. Maybe means a guy who runs the castle? I doubt there was a castle “maker” occupation.

Some information [here](http://www.etymo-logique.com/le-mot-du-jour/chatel-luc/) (in French). The gist is:

The office of castellan / chatelain often gives rise to the surname Châtelain / Châtelin. It’s just a job, not necessarily anything especially noble. For smaller properties, the diminutives Châtelard or Châtelet might be in force, or further west, Châtelier / Lechatelier.

Plus, of course, surnames often derive from place names.

I suspect it’s more likely to derive from a toponym, since castle-related toponyms are ludicrously common.

A carat is a measure of weight (diamonds) or purity (gold). The ^ sign is referred to as circumflex, or (in French) accent circonflexe. You may be thinking of the ‘caron’, or more commonly háček, which _is_ a diacritical sign, but not the one used in French - instead it’s the ˇ sign, like the one used in my username.

No, he’s thinking of a [caret](http://en.wikipedia.org/wiki/Caret), but you’re right that this is not the name of the diacritical mark.

It may be so, as it seems that there are indeed [a few places](http://books.google.co.jp/books?id=AdAYRLukKUcC&pg=PA1467&sa=X&ei=UeI2U-2NJY6okgW_o4HoDA&ved=0CFYQ6AEwBQ#v=onepage&q=%C3%A9tymologie%20ch%C3%A2telier&f=false) named Le Châtelier in France.

However, that doesn’t really answer the question, because you’re still left wondering why these places are called this way. As **Dr. Drake** ’s cite shows, the word breaks down into _Châtel_ – castle, and _-ier_. In this context, this suffix denotes an occupation. See for instance _hôtel_ -\> _hôtelier_. Following this line, a _Châtelier_, would be someone whose occupation is related to castles.

On the other hand, this [90s-tastic page](http://www.infobretagne.com/chatellier.htm) about a place in Bretagne called Le Châtelier claims it is named after a Roman observation fort, the _castellum_. Note that this is the same Latin word from which _château_ derives, and so here, the _-ier_ suffix is likely a diminutive.

-ier is never a diminutive, it clearly refers to some type of profession. I can’t find anything on the French, but in Dutch, there’s a profession called ‘[kastelein](http://nl.wikipedia.org/wiki/Kastelein)’ derived from ‘kasteel’ (castle) that I think is related. I thought it only meant barman or landlord (of a pub or inn) but apparently it derives from a feudal position that was something like a steward or placeholder of some castle owner.

I immediately thought of “hôtelier”. This would be someone who runs an hotel. My guess is that a “Châtelier” runs a château.
