unspecified 是形容词，不是动词，不能直接带宾语。表示“未指明”可以用 leave + 宾语 + unspecified（或 did not specify），所以应把 unspecified 放在宾语后作补语。
We agreed to meet at a not specified place.We agreed to meet at an unspecified place.
not specified 是“not + 过去分词”构成的短语，作定语时通常后置或作表语，不能直接放在名词前；名词前作定语应用形容词 unspecified。

Learner notes
Memory Tip
记法：specified是‘明确指出的’，加否定前缀un-就是‘未特别指定’——想象表格里空着的那一栏，写着unspecified。
Context & Register
语域：mixed 常见场景：法律/合同文本、新闻报道、学术写作 该词通常用于书面和较为正式的场合，如法律、学术或新闻报道；日常口语中更常说 not specified。具体语气取决于搭配，整体偏正式但非极端正式。
Pronunciation & Spelling
能和 unspecified 押韵的是 specified（重读音节 /spesɪfaɪd/ 一致）；其余几个词虽以 -ified 结尾、拼写相似，但重读元音不同，发音并不押韵。
