I don’t like the sound of the word “partner” when it is applied to human relationships….It feels chilly and cold not like a descriptive term for someone you love.
Partner as a description of someone one is involved with in a relationship is a somewhat recent addition to the public lexicon….The latest edition of Oxford's Dictionary does include this as a third definition….The other two being about business involvement or any activity an individual might be doing with another person.
The word “partner” has evolved I believe as a gender neutral politically correct term of description because of the large number of married couples who stay together for years and may even have children but never legally get married and gay couples who lack legal recognition of their marital status.
I just think it feels like a very impersonal word without any sense of what two people can mean to one another….Wife, husband, girlfriend, boyfriend are all better I think even lover which seems more vulgar as it refers to the sex act.
That’s just my feeling and I mean no disrespect to the different classifications of relationships in today’s complicated culture….I just feel words that convey that two people are in a relationship should carry more warmth and not be so legalistic as if their love was on a contractual basis
