This verb is almost always used with 'to' when specifying what control is imposed ('subjected to harsh treatment'). In passive constructions ('were subjected to') the meaning often overlaps with 'cause to experience' (the rejected_additions sense). The active voice ('The army subjected the town') carries the stronger subjugation meaning.

Distinguish from sense adjective/1 (LIKELY TO EXPERIENCE). In this sense, 'subject to' means 'conditional on' — it is about a requirement that must be satisfied, not about vulnerability. The same 'be subject to' structure carries two different meanings depending on context.

文法句型
be + subject + to + noun phrase (a ruler, a government)
用法筆記
This sense is closely related to noun sense 6 (CITIZEN UNDER MONARCHY) and verb sense 1 (SUBJUGATE): if a people are 'subjected' (verb), they become 'subject to' (adj) a ruler, and individuals in that situation are 'subjects' (noun). The three POSes form a coherent meaning cluster around control and subordination.
