(ISP) I think "data" can be both but I agree that to insist that it is always plural is pretentious and a bit annoying, a bit like government propagandums.
(Phil) Don't quite remember 'em, but if you say so. :-)

[Phil] Thanks. I'm not overly conversant with WWII UK memes unfortunately. In fact, Mr. Chad (known elsewhere as Kilroy) is the sum total of my knowledge of the matter. Or was, since I now know something else thanks to you and FGZStar.

I recognised the reference to 'Keep Calm and Carry On' - available on mugs near you - but still don't see what FGZstar means. I'm happy to accept that it's just a generational thing.

Datum and agendum are singular. One singular piece of data and one singular thing to do, rather than a list. The minute it is two (or more) they become data and agenda. So, "What's on the agenda?" is correct being people are going to expect more than one item. If I say the only thing on the agenda is the meeting, that's wrong, it's the agendum. Yes, I am just being a grammar nazi. I don't really care that much about those words.

I'm trying to do the hidden words thing.

Is this how I hide words?

I figured that out!

Hidden text

I must be smart!

At least, that is not when trying to make text small.

[INJ} I am given to understand by today's youth that "to bail" would indicate giving up in a dramatic way. It would appear to come from "bailing out (of an aeroplane)". Incidentally, "Keep Calm and Carry On" is available on a mug in my own kitchen.

[Kagome...] If you have a lst of things to be done (from the latin gerundive), or an agenda, and it only contains one item, it is still a list of things to be done. So I disagree, and would say that an agenda for a meeting is always an agenda, regardless of how many items are on it. More specifically, each item on an agenda would be an agendum.

[Kag] And you got the singular of Nazi wrong too; it's Nazus. :-)

[Phil] I have it on very good authority that each thing on an agenda is an itum.

[Phil] I have a "Keep Calm and Carry On" t-shirt. frogstar has one that says "Now Panic and Freak Out". To date I don't think we've worn them at the same time.

[KS] A datum is a data point and so is a count noun with a plural of data. However data meaning information is a mass noun and takes a singular agreement.

The whole 'Just Bail' Idea related to something one of the guys I know from my accommodation, who once said 'let's just bail' at a party, and so it stuck, and got written on a large board and put in the window. It was then at a recent poster sale that we saw a 'keep calm' poster, and decided to change it. It was initially going to be 'Just Bail', but this would not fit with the whole idea of an odd number of lines, so the expletive got added. We are now planning on getting the poster printed up at A2 or A1 size, and put on the kitchen wall.
