Are there etymology dictionaries for French available on the Internet? To wit, what's a French equivalent of http://etymonline.com/?

I already know about
TLF informatisé (TLFi), but often, it does not retrograde to Latin and PIE etymons;
Littré suffers from the same problem as TLFi, but is abrupter.

PS: This Area 51 question is similar.

If you have access to a good library you can consult von Wartburg's Französisches Etymologisches Wörterbuch in 25 volumes. There is also an abridged French translation.


The Littré is available online free of charge. It is old (1877) but can provide some interesting etymological insights

  • Thanks, but Littré lacks sufficient details for many entries. I did know about it before, but I should've professed this. So would you mind please converting your answer into a comment?

Wiktionary has etymology entries going back to Old French, Latin, and Proto-Indo-European (PIE), e.g., https://en.wiktionary.org/wiki/bleu#Etymology.


The text of "An etymological dictionary of the French language" is available at https://archive.org/stream/etymologicaldict00bracrich/etymologicaldict00bracrich_djvu.txt


Limited etymological info for French (40,000 words), along with around 20 other languages: https://etymologeek.com/fra/a
