请问：I couldn't care less.中的couldn't表示什么意思?

I couldn't care less. 请问：I couldn't care less.中的couldn't表示什么意思? i couldn't care more这句话啥意思蒽? 为什么i couldn't care less 译“我不感兴趣” I always couldn't care more about you ,always very much,I care for and treasure your ,your to know. i couldn't agree I couldn't help i couldn‘t是什么意思 couldn't care less歌词的中文意思I couldn’t care less if you don’t love meI couldn’t care less if you don’t want meBut I gotta confess that when you abadoned my heartYou know you tore it apartI guess I’m okay now in every wayI manage I don't care I ALMOST COULDN'T 还是I COULDN'T ALMOST? I couldn't care less.从字典的意思看是我根本不在乎.为什么是这种解释呢,我认为care less本身就是不在乎,如果加个couldn't那不就是不能不在乎的意思吗, i probably couldn't造句 words i couldn t say i couldn't help but I couldn't agree more. i couldn't stop thinking I couldn't miss you
