?? Why is the word unuseabe by a speech writer? I use the word in my speech all the time. Okay, sometimes. Okay, I used it once about 50 years ago when I first learned it. Curious.
I think it’s good to elevate ones level of speech. I use words like this all the time. when my youngest daughter (now age 23) was in Kindergarten, she had wild curly hair. she told her teacher “my mom said my hair was an abomination today!” the teacher LOLed.
