Hi!!
Could you please tell me the difference between
"It's quite cold. You'd better wear your coat" ve and "It's rather cold. You'd better wear your coat"
Thank you arasındaki fark nedir?Sadece örnek cümleler vermekten çekinmeyin.

the UK has a quite entrenched class system, and to my ear, the difference between the two would reflect a class difference.
quite cold would be the most natural way to say it, and would reflect every day speech.
rather cold sounds a little more "posh", and I might expect that the speaker had attended a public school (note: in the UK the term public school actually means a private school that has to be paid for 🤷🏻‍♂️)
as a more extreme example, you could say
frightfully cold, which would sound quite pompous (unless it was been used to describe quite extreme weather conditions)
