As Maw Broon says, there is a space :- disinte rested ( disintegrated, disinterred) I , sort of read them both, when I saw the title, apologies Blue45Sapphire, it's just the way my aged mind works.
Would someone please be kind enough to point out my spelling mistake? If I have made one then I will put my hand up and am truly mortified. I do own up to leaving the close bracket off the end of the paragraph, though.
Disinterested is a useful word and it should not loses that special meaning. Un- and dis- are both prefixes to turn an adjective negative, but here there is a different meaning. I can show interest in something but if does not affect me personally, then I am disinterested.
It had been niggling me too, but I hesitated to raise my head above the parapet, having been shot down in flames before now. Spelling mistake? The superfluous space?
I am seeing this more and more these days, people saying or writing disinterested when they mean uninterested, and it really annoys me. I was brought up and taught that disinterested means impartial or unbiased, and uninterested means that you're just not interested in something. The other one is the 'font' of all knowledge instead of the 'fount' (unless, of course, I've been saying it wrong all my life!
