They tend to be for the wrong word altogether, so they are really awful.
They are not just bad, irrelevant definitions, they are worse than that, as they define some other nearby word, and cause mental interference as I try to think about what the sentence means.
Can we have an option to turn them off completely?
Thanks for asking. I disabled contextual meanings, and the dictionary popup now appears almost instantly. Previously it could be a real struggle to get the non AI meanings to populate if at all.
