What does the word canicule have to do with heat waves and dogs? Let’s find out.
In French, canicule [ka.ni.kyl] refers to a heat wave or hot spell, the dog days of summer, or Sirius (Canis Major / the Dog Star). A heat wave is also known as une vague de chaleur. In English, it’s an old word for dog days. It comes from Latin canīcula (puppy), from canis (dog, hound), from Proto-Indo-European *ḱwṓ (dog) [source].
Related words include caniculaire (scorching), chenille (caterpiller), chien (dog) and chiot (puppy) in French, and canine (of or pertaining to a dog), cynophile (a dog lover) and kennel (a dog house) in English.
What are the dog days (of summer)?
- (archaic) The days following the heliacal rising of Sirius, now in early August at dates varying by latitude.
- The unpleasantly hot days of late summer.
- Any similar period of inactivity, laziness, or stagnation.
The expression dog days is a calque of Latin diēs caniculārēs (puppy days), a calque of Ancient Greek κυνάδες ἡμέραι (kunádes hēmérai – dog days). The return of Sirius to the night sky (its heliacal rising), occurred in antiquity around 25th July in Athens and 29th July in Rome, and was considered by the Greeks and Romans to herald what were considered the hottest, least healthy, and least lucky days of summer [source].
Bad weather is also associated with dogs in French: temps de chien (‘dog weather’) means bad, filthy, dreadful or awful weather. Similar associations are made in Italian: tempo da cani (‘dog weather’ – bad or rotten weather); German: Hundewetter (‘dog weather’ – bad weather), and Dutch: hondenweer (‘dog weather’ – particularly bad or rough weather, the kind of weather when it is raining cats and dogs) [source]. In Welsh, unsettled weather is tywydd llwynog (‘fox weather’) [source].
Is bad weather associated with dogs, or other canines, in other languages?
Incidentally, the letter R was known as littera canīna (‘dog’s letter’) in Latin because its trilled pronunciation sounds a bit like a dog [source].
