Survival in a way. The reason for writing on this thread was to show that it is possible to learn a language fluently as an adult, I know from personal experience that it is true.
I also know that English people who live in English enclaves, in Spain for example, have difficulty in picking up the language as they are mainly communicating in English and local traders learn to do the same, motivated by profit of course.

Our French teacher, Mr Corfield, certainly knew how to get most of his class of 30 plus 11 year olds interested in the subject.

He turned many of the lessons ( sadly not all) into a sport.

French Cricket.

Rules.

Class divided into 2, left and right side of the classroom.

A book of French prose handed to all the pupils.

1st batsman of side A reads from the book, and for every word pronounced correctly, a run is scored.

If any the fielding side (B) thinks a word has been pronounced incorrectly, he can appeal, and if the appeal is successful, a wicket is down. If not, 5 runs added to the score.

Kept us enthralled for the whole lesson.

I'd only just turned 20 when I spent a year as an exchange teacher in a German school. It was a bit unnerving at first, having to assert your authority over a class of 18-year-old Abiturienten. I just had to keep reminding myself: 'Who won the bloody War anyway?'

I can't say it was a great help for making me more fluent in German, but that was on account of me being hard-of-hearing. It was no different from English really: one-on-one conversations, where I could lipread, were feasible, but sitting in the staffroom or the skittle alley or the pub, I had no idea what was going on. I still absorbed enough to come back to England speaking German way better than any other students in my university year though, because they had all spent their year as exchange students in German universities. Consequently they spent all their time with other English exchange students.

Luckily none of the teachers realized they were employing a half-deaf teacher, or I could have been sacked. The pupils soon cottoned on though, when they noticed I couldn't hear the bell for the end of lessons. It became a game to see how early they could get a lesson to end, by claiming the bell had rung and I hadn't heard it.

That's the only Latin you need to know

But if you've had a classical education, how would you know what it's like for those that haven't?

Everyone can have the world at their fingertips, I often do when I've had 12 pints of lager and I'm crawling home

Dr Crippen: From working in a couple of offices back in the 1980s. I was translating patents and medical texts, and the staff who had modern language degrees, but no O levels in Latin or Greek from school, simply gave up. (In fact, they mostly got promoted to office managers, on the basis that you couldn't go promoting people who actually had enough knowledge to wade through 200 pages of organic chemistry or reams of LD50 tests on Wistar rats.)

Akabula: Here's the (poorly) translated abstract of a study done a few years ago on the effects of artificial sweeteners. I've chosen it, because it was what I happened to be reading before I came back to this thread:

Modified High-Density Lipoproteins by Artificial Sweetener, Aspartame, and Saccharin, Showed Loss of Anti-atherosclerotic Activity and Toxicity in Zebrafish

First Online: 21 August 2014

Abstract

Safety concerns have been raised regarding the association of chronic consumption of artificial sweeteners (ASs) with metabolic disorders, especially in the heart and brain. There has been no information on the in vivo physiological effects of AS consumption in lipoprotein metabolism. High-dosage treatment (final 25, 50, and 100 mM) with AS (aspartame, acesulfame K, and saccharin) to human high-density lipoprotein (HDL) induced loss of antioxidant ability along with elevated atherogenic effects. Aspartame-treated HDL3 (final 100 mM) almost all disappeared due to putative proteolytic degradation. Aspartame- and saccharin-treated HDL3 showed more enhanced cholesteryl ester transfer activity, while their antioxidant ability was disappeared. Microinjection of the modified HDL3 exacerbated the inflammatory death in zebrafish embryos in the presence of oxLDL. These results show that AS treatment impaired the beneficial functions of HDL, resulting in loss of antioxidant and anti-atherogenic activities. These results suggest that aspartame and saccharin could be toxic to the human circulation system as well as embryonic development via impairment of lipoprotein function.

The terms I've highlighted, because they're the sort which I would normally skip over:

lipoproteins: if you know that λῐ́πος is a noun meaning 'fat' in Ancient Greek, then you can guess that we're dealing with proteins which transport fat through the bloodstream here (as well as guessing that in another context liposuction involves sucking away fat).

in vivo: pure Latin, meaning a test carried out within a living thing (as opposed to 'in vitro' (literally 'in glass', i.e. in a test tube)).

anti-atherosclerotic:  σκληρός means 'hard' in Greek, so we immediately know we're dealing with something with an anti-hardening action; an atheroma happens to be a mass of diseased material in an artery, and also happens to be derived from the Greek, but I didn't know that. However, at least with a bit of Greek we know what sclerosis is, so we can look the rest of the term up and not just glaze over it, which is my whole point.

putative: putare means to think or to guess in Latin, so we know the authors are supposing that the effect in question is taking place, without necessarily being certain. This is important - this might be something you'd want to investigate further, but, to spot that, it helps to be sure what 'putative' means, rather than just gloss over the word.

proteolytic - difficult one this, but if you're familiar with processes such as electrolysis, where compounds are broken down using electrolytes, then you could guess that something's being broken down here, and, as it happens, it's Greek again -  λύσις, meaning something being loosened, but I didn't know that. After all that, proteolysis turns out to means proteins being broken up.

Maybe it makes no difference that I can just about decipher this text, thanks to Latin and Greek - after all, anyone who's seen the the effects on John McCririck of drinking too much  Diet Coke is going to avoid this stuff in any case. But it's nice to be able to understand precisely why it might be making you feel lousy.

An everyday example would be where something in a written document is scored out with Stet written above.
"What does that mean" the first time encountered. Getting the explanation one remembers and moves on. No need to spend years studying.

Looking at a can of sugar free irn bru.
Few words I don't know the meaning of but could look up.
But so what? Unless we allow and accept the 'experts' to do their job we'd spend our whole lives analysing everything we encounter.

Yes, but my point is that if you have a knowledge of Latin and Greek you don't necessarily have to slog through an analysis, or key every other word into Google, in order to understand subjects on which you're not an expert.

Half the English language is derived from Latin, and it's the half which comprises nearly all the unfamiliar jargon used to impress and obfuscate.

Anubis is an Egyptian god with a head of a jackal.

It comes from Proust and your translation fits the scene . Thank you Screaming .

FOEDUS UEFA gentes - quae est infernum, est?

No the reference makes perfect sense now . Proust is hard work but well worth the effort .
It only takes me 14 months to read the original these days .
The Sporting Chronicle Handicap Book was a wonderful publication . Those were the days!

I think it’s good that we have Latin because it’s taught in good schools

maybe the two things are related

Many they think Latin is elitist now ,

That’s only because bad schools don’t teach it , what does that tell you

Get the ones who do to pretend they don't

That’s the way of most things anyway and you  have only to look at the difference Latin makes to a school

And English of course , Latin was too difficult for the natives
