insatiable 作表语时不能直接接 for 加对象。常用搭配是“have an insatiable + 名词 + for”，如 have an insatiable desire/appetite for；直接用 be insatiable for 不自然。
针对“无法满足的/不可能被满足的”（insatiable）这一义项，satiable 是直接反义词，表示“可满足的”；常与 desire、appetite 等搭配。注意 satisfiable 虽也可表示“可满足的”，但更侧重条件或要求，日常指欲望时较少用。
insatiable 描述人/欲望等主观上永不满足，常含贪婪、不知足的意味；unsatisfiable 强调要求、条件等客观上无法被满足。修饰对象和语感不同。
insatiate 与 insatiable 同义且词形相近，但 insatiate 是古旧/文学用词，现代英语几乎只用 insatiable。语体差异很大。
insatiable 指“无法”满足（性质）；unsatiated 指“尚未”满足（状态），是短时感受而非固定性格。
