This isn't a spoiler, because the word I want to discuss wasn't accepted at all.
Nor am I suggesting it as a new word.
In today's challenge game (in which I am yet to find the seed word) I confidently played 'broddle', expecting it to be accepted as common. But Chi wanted nothing to do with it, not even accepting it as rare.
To my surprise, further research revealed that it's a Yorkshire dialect word. My husband and I were both born and raised in Yorkshire but haven't lived there since we were 18, and it's 45 years since we left the UK altogether. In all that time we have probably being reinforcing in each other the use of this word which we believed to be standard English (and have probably passed on to our Australian-born children).
It's not a word we would use very regularly - it means to poke something, or pierce it. You might use a length of wire to broddle a small ventilation hole in a machine, to clean out the hole if it had become clogged with grease or dirt, for example.
I'd be interested to know if any other forumites are familiar with the word. I don't think yorkshirerose is a forumite, unfortunately.
