So, have you ever wondered which words really irk usage commentators? Here's a way to find a bunch of them. Select Collegiate Dictionary as your reference and click on Advanced Search. Type disapprove in the Usage Paragraph box, and then press the Search key.

That search netted ten entries, ranging from a long paragraph on ain't (“widely disapproved as nonstandard and… flourishing in standard English”) to two sentences on the pronoun such (“for reasons that are hard to understand, commentators on usage disapprove of such used as a pronoun”).

Other entries with paragraphs noting disapproval include don't, enthuse, foliage, get, nuclear, prove, providing, and split infinitive.

Then if you want more, you might want to try a search with dislike in the Usage Paragraph box. You'll see what commentators – and Merriam-Webster editors – have to say about forte and leave.

And, if you're still hungry for controversy, try the same search with object and mistake in the Usage Paragraph box. You'll find plenty more.
