OK, would you care to point out which ones committed this faux pas ?
If any of the Dynamics are guilty, I will gladly fix them.

In Latin, certainly, but in English it seems that "agenda" is absolutely accepted in the singular, with "agendas" in the plural. This, mind you, is according to my Oxford Canadian dictionary, but I doubt an American version would be any different.

In fact, "agendum" is not in the Oxford.

–noun, formally a plural of. agendum, but usually used as a singular with plural. -das or -da.

Firstly I think the problem is only in the planner kits, but I will check the dynamic ones later if I can and see. Thanks!

And yes, I know the inaccurate use has crept in, although I suspect less here than in America (I am honestly not a snob over this, in many ways I think much American pronunciation etc is better), but I care about the exact accuracy and I know a lot of people who would agree. Being a word which IS Latin, I like the Latin rules to apply!

Thanks very much everyone, and I'm grateful you haven't laughed at me :)

In latin agenda means "things that have to be done", a gerundivum form for those with some knowledge of latin (sorry I don't know the english word for gerundivum). Which is why our word agenda in dutch means planner, because you write down your todo's in them. The singular is indeed agendum.
But the things you write down on these lists are things to be discussed with or communicated to someone else a la gtd. So technically the word is not correctly used here at all, whether in singular or in plural form.
However, the lists are designed to hold more than one item per person, so the plural is "less incorrectly" used here in my opinion.

can I get my fix of pen and paper AND a language lesson. Gosh, I'm such a geek!

No ... me ... pedantic? [end sarcasm]
:D

According to an elderly lawyer I worked with in the 1980's who was then approaching 90 and, from his attitude, considered Dickens to be a slap-dash young thing who didn't know how to write correct English...

Agenda is a list of agendum.

Agendum are the individual items on an agenda.

So a meeting agenda consists of many individual agendum.
... Making a coffee break in a meeting an agendum. ;)

This means - if the template has one line on it then it can be an Agendum template. If you can record more than one item then it's an Agenda.

This has been a most interesting thread. But it does seem like "agenda" should be there to stay.

As a native speaker of French, and only a second-language speaker of English, I often cringe at the way many French words are used in the English in more or less appropriate ways, to say nothing of the spelling or pronunciation. But languages evolve. The French language, for example, has many words starting with W, but all of them come from other languages. Like "wigwam." There were no proper French words to designate those realities, so foreign words were "borrowed" and adapted. Because I live in British Columbia I have the chance of seeing and hearing some words as they are spelled and said by First Nations people, which is different from the way English and French has pronounced them.

So languages evolve. If one really wants to be a purist, then, Ygor's "agenda" should probably be a "planner" and no word of latin origin should be used at all to avoid _faux pas_. However, the word "planner" in English, etymologically speaking, arose from the French "plan," which itself comes from the Latin "planum," which had a different-enough meaning to NOT be used on the cover of an agenda.

This being said, I'd love Scylax (the OP) to go after the folks who have ensconced "status quo" in the English language. It's "statu," no ending -s!! To each their pet peeve.
