Out of now here / no here 點解　？？

我估應該是English Idioms(習慣用語) --- out of nowhere

解釋一. (從不知名; 從不為人注意)

He came from out of nowhere into a world-famous figure.
(他從默默無名一下子變成舉世知名的人物.)


解釋二. (不知從那兒來; 突然冒出來)

He appeared out of nowhere and stopped me.
(他突然冒出來把我攔住.)

the word nowhere should be a mixture of no and where, not now and here
