The 58 most commonly misused words and phrases

I’ve known to avoid most of these, but I must admit that I’ve been misusing the following for years:

Disinterested means unbiasedand does not mean uninterested.

Nonplussed means stunned, bewildered and does not mean bored, unimpressed.

With regards to the other words in the list, I still prefer using the singular datum over data where possible. I remember once being “corrected” by my upper secondary school teacher because of it.
