Hmmm - thank you: I'll try that! (Ho, Jeeves! Quick: get our spaceship ready, for tonight, we're visiting the Sun!)
The word tip/clue suggested both "warm" and "hot", but "warm" was rejected the last time I chose it, so I chose "hot" and it was accepted. And yet, oddly enough, I've said, and heard people say (in English), "The sun is very warm today," which I take to be a case of understatement - even though we're Americans, not English/British, and they're the ones famous for understatement! I'm accepting that "varma" is "hot", since those experienced in Esperanto say it is so; yet I wonder if the word tip/clue that is given when hovering of the word, might need amending?
The sentence is more poignant, as our local weather's begun heating up for the summer; highs in the 90s (F) or mid 30s (C) are appearing. It's becoming mega-warm!
Is it common practice to roll or tap one's Rs when pronouncing Esperanto?
