past是介词还是形容词?

past
n.
过去, 往时
adj.
过去的, 结束的
prep.
越过, 晚于
名词 形容词 介词 都可以

要看怎么用了

past- it is not an adjective/noun or verb
same tense with words like on by through

形容词,查一下字典就知道了

既是介词又是形容词
如:The days are past / in the past few years(形容词)
He walked past the school/ he is past 40(介词)
此外,还做名词
He speaks little about his past
