1.
"That begs the question." To beg the question is to make an argument that assumes its conclusion in its premise. If you think an observation prompts a question, it raises that question.
2.
"Less" + count noun. This one happens all the time. It's simple.
Mass noun + larger than = more
Count noun + larger than = more
Mass noun + smaller than = less
Count noun + smaller than = fewer
3.
Who and whom. It seems absurd to me that people don't understand the difference between the subject and object of a sentence (or even understand that they exist).
The subject of a sentence is the party that is acting.
The object of a sentence is the party that is being acted upon.
There are direct and indirect objects, but for this error they aren't relevant. To use who and whom correctly you only need to know that "who" relates to the subject and "whom" relates to the object.
4.
"Myself" instead of "me". "Yourself" instead of "you".
At least people who make this error are trying to get it right. Never-the-less, myself and yourself are reflexive pronouns and should only really be used when me/you has already been mentioned in the same sentence. Some people like to say things like 'It's not for me, myself.' This is to give emphasis (which you don't need in those places), but I think it sounds silly.
There are so many more, but these are the ones that grate against the sides of my brain.
EDIT: It only just occurred to me that none of these refer to opinions and ideas. Perhaps I've a higher tolerance for nonsense than I thought.
