I'm really confused between these three words. Most dictionaries say that all of these words have a meaning of honour. Here's what I understand, though I don't know if its right.
光栄{こうえい} ー Honor - (I.e: It is my honour to meet you / I am honoured to meet you). I don't know if this word has any other uses, though.
名誉 {めいよ} ー Prestige, credit - (名誉ある賞): Prestigious award.
栄誉 {えいよ} ー Honor with a meaning closer to "glory". If this is the case though, how is it different from 栄光?
Thanks in advance
