Bonzo, you are an idiot. "Partner" includes spouse (ie husband/wife) civil partner pursuant to the Civil Parntership Act, and person with whom one shares life/emotional existence/bed/sex/whatever whether or not in one of the previous categories. It's a meaning that has evolved to replace "mistress" or whatever the male equivalent was, partly because that expression conveyed the concept that the master paid for the mistress (or gender reverse) which is not necessarily the case since women can and do earn as much as men (although they do not always get treated fairly in the earnings market). Grow up.

There is much to be said for a gender neutral vocabulary, but it takes time to create a suitable set of terms that are not ungainly.

If by "maid" you mean "cleaner" then "cleaner" is a good choice of word. Is there any reason you prefer a female cleaner? You give many indications of sociopathy, and I would not put it past you.

Nonetheless, I should concede that my cleaner, my gardener, and my painter and decorator are all female, athough when I last had a specific office cleaner he was male. Nowadays I am my own typist and filing clerk, but when I used secretaries they were often female, but occasionally male, as is often true of nurses and primary teachers. I see no reason why any such person needs ot be of a specific gender. I know one young woman (nobody who is anybody says "lady") who has recently qualified as a fireman (I eschew "firefighter" because the word has been corrupted by the inelegant use of "firefight" for "gun battle") and if you are worried about her upper body strength when fighting fires, I suggest you go and armwrestle with her - I value my guitar playing arm too much to do so.

Gender stereotyping is a lot of nonsense. We are more creatures of the mind than of the body, and minds, like angels, are (mostly) sexless.
