Can moonie be used as an English name?

No, it's not an English name. Foreigners will laugh at you.

We have seen people name themselves Rain, sun, rainbow, snow, storm or their adjectives Sunny or rain, but they are all bad English names. In America, no one will choose natural English words as English names. If you have such a name, Americans will think you are strange.

These words have interesting meanings, or some of them suit your personality. For example, a lively and bright girl chose Rainbow as her English name. But we must consider whether westerners accept such English names, so it is not a good choice. Westerners don't respect such names and even laugh at them. So it is called Iris (which also means rainbow), which is the English name used by the Royal West Renye Fang.

There are many good English names that foreigners respect and accept. Please choose the English name that suits you best.
