Seem to have the same concern as other people. I put 'The boy has a hot scarf' Why not accepted? Considering when you put your mouse over 'chaude' it says 'hot/warm' this should most definitely go through as correct. Duo, sort this out.
Regarding chaud, when is hot hot and when is hot warm. Because there is a difference in how each feels, but apparently not a difference in the word used to describe the feeling. Besides, it is used inconsistently here. Please explain.
I, too, would like to know this. I think I've read that before about other adjectives, but haven't been able to find a clear rule discerning when to have an adjective that normally follows the noun precede it.
