Sunny

Sunny derives from the English word "sunny," meaning full of sunlight or cheerful disposition, itself from the Old English sunne, meaning "sun." As a name, it emerged as a nickname for bright, cheerful individuals before taking on an independent identity. It is one of those names that carries its meaning right on its surface — you know exactly what kind of personality is being described.

Sunny ranks #132 among America's most popular pet names, and it might be the most self-explanatory name on this list. A pet named Sunny has been observed, loved, and named by someone who saw genuine light in them — the kind of companion who makes a room brighter just by entering it. The name works for any gender and any species, which contributes to its broad appeal. There is also something optimistic about choosing Sunny: it is a name that belongs to someone who chooses to see the bright side.
