Jovial
Etymology
From the astrological Latin phrase behind "of Jupiter" — Jove being the alternate name of the god and planet Jupiter. Those born under Jupiter’s influence were thought to be merry, generous, and sociable, since the planet governed a benevolent temperament. The astrology faded, but the sunny, expansive character it named stuck to the word.

What it names
The expansive good cheer of the host who keeps the whole table laughing and refills everyone’s glass.
