Is there an idiomatic way to translate “less and less”. I.e., I want to say that something happens less frequently than before and it is in continual decline. For example:
People are using Facebook less and less.
I think in French you could say “de moins en moins”.
Probably the easiest way would be to use "pli kaj pli", which is idiomatic in Esperanto, and then just take the opposite of what you wanted to say.
Homoj uzas Facebook pli kaj pli malofte.
That said, that has a slightly different intensional meaning. I haven't really heard of a more direct equivalent, though. I suppose it would have to be,
Homoj uzas Facebook malpli kaj malpli (ofte).
...but that doesn't really sound as good, probably because of the fact that malpli has two syllables, or just perhaps it isn't used much, from what I can tell. Still, I suppose you could introduce it; you would be understood, at least.
I think
Homoj uzas Facebook ĉiam malpli.
is a good way to say less and less or decreasingly or
ĉiam pli malmulte
