blissyoudaoicibaDictYouDict[bliss 词源字典]
bliss: [OE] Despite its formal and semantic similarity, bliss has no connection with bless. It comes ultimately from Germanic *blīthiz ‘gentle, kind’, which is the source of English blithe ‘happy’ [OE]. The addition of the noun suffix *-tjō produced the derivative *blīthsjō, which entered Old English as blīths ‘happiness’, later reduced to bliss.
