Earth to namers: not all people who name their babies take their meanings for granted. For example, why do people name their child Cameron even though it means "crooked nose"?As for Aries itself, it's a very powerful and dignified name. People who name their child this are not astrology nuts; they name their child because they like the name!
I personally love the name Aries. Like others have commented, it sounds more feminine to me. Although I think it could work for a guy too. The zodiac does interest me a lot but personally I think Aries would be a really cute name just because of how it sounds to me. It sounds really light and airy, delicate as well.
Aries may well be a masculine name, but we have a beautiful female granddaughter named after the zodiac sign she was born under. Aries actually SOUNDS more female than male. We rarely have anyone ask why she's been given a male name.
