If sjmaaxq got it wrong, could I impose on your time and ask you to explain how? In your earlier response you said:
In reply to:
My position is that of a right Angle ;)
1. The suffix ~oid originally meant ‘like or sharing some characteristics’
http://www.etymonline.com/index.php?term=-oid
2. When it got appended to ‘fact’, the resulting word got used to initially mean ‘like a fact’ in an ironic deprecatory sense
That is the sense in which sjmaxq and I use it. Then you say further in your reply,
In reply to:
3. Because these were often spurious and short items as Bing notes, it subsequently picked up the connotation of ‘brief fact’
4. By retrofitting this has extended the denotative value of ~oid to include ‘small’, making it similar to ~ette
5. Although the majority of the usage panel are still mostly uncomfortable, it’s a change, it’s happening, and it’s a comparatively rare example of one you can actually observe in progress.
You talk about it "subsequently picking up a new connotation", and that there is "a change happening". If the change of which you speak is not the shift in the meaning of factoid from its initial one to the new one, what is it?
All needling aside, you've piqued my curiosity now, and I want to understand what you're saying. Or rather, I want to figure out why I have not been able to understand it up to this point.
