late 14c., "taking, seizure," from Old French capcion "arrest, capture, imprisonment," or directly from Latin captionem (nominative capito) "a catching, seizing, holding, taking," noun of action from past participle stem of capere "to take" (see capable).
From 17c. used especially in law, and there via its appearance at the head of legal document involving seizure ("Certificate of caption", etc.), the word's sense was extended to "the beginning of any document;" thus "heading of a chapter or section of an article" (1789), and, especially in U.S., "description or title below an illustration" (1919).
caption (v.)
by 1901, from caption (n.). Related: Captioned; captioning.
中文解释
1、capt- + -ion.2、字面含义：taking, seizure.3、由于该词最初主要出现在“逮捕证明”("Certificate of caption", etc.)的法律文件的标题上，由此，其含义得到了扩展，表示任何文件的标题、开头、说明。
