التركية النطق dôg deyz
/ˈdôg ˈdāz/ /ˈdɔːɡ ˈdeɪz/
علم أصول الكلمات () 1538, from Latin dies caniculares, translated from Ancient Greek; originally from the hot summer days (in the Northern Hemisphere) when Sirius (the Dog Star), in Canis Major, rose and set with the Sun (heliacal rising). The Greeks also made reference to these "dog days", and for the ancient Egyptians, c.3000 B.C.E., the rising of this star coincided with the summer solstice and the start of Nile flooding. The "dog" association apparently began here, as the star's hieroglyph was a dog, a watchdog for the flooding of the Nile.
