It's too cold outside today請問outside 是什么詞性?名詞嗎？

副詞詞性，今天外面很冷

outside 在這里是副詞

不是，outside在本句為副詞性質(zhì)，作地點狀語；outside具有雙重屬性：副詞和介詞，區(qū)別是作介詞后面必須接帆頌虧名詞態(tài)神。櫻備eg.
he is playing with neighbours outside.
副詞性質(zhì)
he is playing with neighbors outside
the yard. 介詞性質(zhì)

這里outside是地點副詞，不是名詞。

It's too cold outside today.
意思是核螞大運：
今天外面很冷。
outside 是副詞，例如：
I stepped outside and pulled up my collar against the cold mist.
我走到外面，拉起衣領(lǐng)以抵改仿埋御寒霧。
Outside, the light was fading rapidly.
在外面，光在快速消失。
