What does sidhe mean in Irish English?

In Gaelic language of ancient Ireland, aes sídhe is a family in Irish mythology, similar to elves and fairies. This word is written in modern Irish Gaelic as Aos Sí, but it is generally translated into sidhe in English, but there is no formal translation in Chinese.

In addition, this word has nothing to do with the mythical blasting, but just happens to be written in the same way.

Receiving Sid is a poem by Ye Zhi, which was quoted above.

The translator calls it Hope God here.
