How to explain 讲 in 讲礼貌 and 讲卫生 In my understanding 讲礼貌 translates as 'be polite' and 讲卫生 is something like 'be clean', but how should I explain the 讲 to a new speaker? I take this as a set phrase, but is there a way to translate the 讲 in these phrases separately?

Wiktionary only provides the following meanings:


explain
discuss
talk


I don't think this fits in with either 讲礼貌 or 讲卫生, so should a new meaning be added to the above list and what should that be?
In this context  讲 is short for 讲究 which means to pay particular attention to; to be particular about.
So you can also say 讲究礼貌 and 讲究卫生.
