I was listening to a podcast and heard the word "anonymat" for the first time - I understood it in context but had to look it up to see the spelling, and was surprised. I would have expected the word for anonymity to be more like "anonymité". I have never seen a noun of this particular form.

I'm just trying to learn to recognize this suffix pattern - if it is a pattern - so that I can correctly parse words like it when I hear them.

What other words have a similar form to "anonymat"?

Examples in english of words like anonymITY would be animosITY, possibilITY, culpabilITY, etc. Is -at similarly a suffix for making nouns, or anonymat just a one-off?

  • E.g. assassinat, prolétariat, patriarcat, sultanat; cognate with English -ate, from Latin -atus. But the use of suffixes may not be the same between the two!

  • Oh wow I've never heard assassinat either. Again I would have expected it to just be a complete cognate, assassination since -ation is such a common french word form anyway and so many such words are the same between English and French. That's exactly what I was looking for. Jul 29, 2022 at 23:35

    You can just look it up. Anonymat: “From anonyme + -at”. Obviously there are more complete reference (but less easy to read), e.g. TLF. Jul 30, 2022 at 5:57
  • Ah, and that page has a link to this list of words, perfect. So, yes, it is a common suffix. "denotes an action or a result of an action". Jul 30, 2022 at 18:35

It's a common enough suffix.

The French -at is cognate with English -ate, from Latin -ātus, which is the Latin perfect passive participle (or from the Latin -ātum, which would be the supine). That also means -at in French has the same root as the verbal past participle ; but of course the two are used very differently.

The venerable TLFi has a whole entry on -at, which splits the senses up into different headings and some examples of each. Note the English "cognate" may use different suffixes.

I.− Le dér. indique une manière d'être en relation avec le sens de la base qui désigne toujours une personne.

A.− Le dér. désigne une dignité, une fonction et plus vaguement un comportement (permanent ou passager, l'état d'une ou de plusieurs pers.).

E.g. Fr. émirat, palatinat, sultanat, voïvodat - compare English emirate, palatinate, sultanate but voivodeship.

Fr. inspectorat, patriarcat; compare these with English inspectorate but patriarchate vs patriarchy, which bears a split in English along semantic lines.

The "behaviour" category is probably the most likely to have a different English suffix; you already have Fr. anonymat vs Eng. anonymity, and I'd say Fr. assassinat vs Eng. assassination (although false friend alert: it's more likely to be equivalent to Eng. murder/homicide, depending on the specifics) is another good example.

B.− Le dér. est un nom coll. désignant un groupe de pers. exerçant la même fonction ou ayant le même comportement, le même mode de vie. C.− Le dér. désigne un système, une organ. soc., jur., etc. :

Compare Fr. prolétariat to Eng. proletariat (note the -at rather than -ate, being a 19th century loan from French into English), versus Fr. syndicat vs Eng. cognate syndicate, but by extension trade union.

D.− P. méton. Le dér. désigne le lieu où s'exerce la fonction (la dignité) ou le temps qu'elle dure.

This is an extension of A, more or less, although TLFi do put Fr. juvénat here; although juvenate is attested in English, juniorate seems to be the preferred term in the Roman Catholic church in the Anglosphere.

II.− Le dér. désigne un produit industr. ou le résultat concr. d'une action.

A.− Produit chim., pharm., etc.

There is a plethora of scientific terms here, this being a productive suffix in the scientific world within many European languages. Fr. substrat vs Eng. substrate, Fr. distillat vs Eng. distillate, Fr. filtrat vs Eng. filtrate.

Note though how Fr. hydrate uses -ate instead, with the same spelling as English hydrate; chemical nomenclature for substances in French requires -ate.

B.− Plus gén., résultat d'une action.

Fr. lysat vs Eng. lysate, Fr. infiltrat vs Eng. infiltrate, but only in its noun form.

Then you have lexemes like Fr. crachat, which is pretty transparent to a French speaker, but doesn't have a cognate in English, and would just be a gob of spit in English if being familiar or sputum for a more elevated register. Similarly, Fr. odorat, which would simply be sense of smell in English.
