J'ai lu...
Le français est richement doté de tous ces mots...
:)

Les noms de lieux qui ont également une signification sont très courants dans le monde entier. Et les noms de personnes. Ma femme Sari en est un exemple.

I read it all with interest. If capitals are used in their proper places and not elsewhere, it shouldn't really cause a problem, but it seems it does and there we are! I understand also that with some languages all nouns are capitalised, not only proper nouns and I can see that is where confusion certainly lies! Not sure if there can ever be a perfect solution.
But I congratulate you on your logical reasoning and efforts, Sami!

If and when people would follow the language specific rules, then for example writing capitalised nouns in German would not be a problem either. So, if one uses keywords in German, then one should try to follow German grammar.

But one reason could be that the words become capitalised by accident. For example, when one opens a keyword field on a mobile phone, to add one for a image here at ipernity, the phone app always first offers the capitalised first letter. Just like one should start any sentence according to somewhat any grammar. And if one does not realize that in a hurry, then the mistake is done.

And then there is also the problem with singular and plural forms, not yet discussed at all.

perso, j'ai toujours le réflexe d'emporter mon reflex :-)

Is it history or herstory? ;-))
Well, it's not a capitonym but it come to my mind acutely. ;-))

Oh, I have one:
When I went from Mobile (Alabama) over this bridge I can't use my mobile. :-)

Nowadays it should be theystory ;-)

Why doctors use Windows OS?
Because Apple a day keeps the doctor away ;-)

Then why window cleaners prefer iOS?
Because they see enough windows at work =D

:-D
