A certain amount of mockery has made me aware that the following terms appear to have fallen out of use:
Tradesmen: Not in common use since the 1950s, I am informed. I do not find this credible.
Pr̩cis Рmeaning summary: I have discovered that any Irish person over 45 knows exactly what this means and younger people think I am describing a press release in my own weird argot.
Maiden Aunt: Not since the early 1900s, I am told. Again, I do not find this credible but yet, the levels of mockery makes me think that perhaps it may have fallen out of favour before most people I know were born.
Updated to add: I am informed by herself that précis is spelt thus with an acute accent, we have checked Chambers dictionary and found she is correct. I have amended the text to reflect this. Do you think we pedants are born or made?
