Connect captioning directly with the verb caption, meaning “to add a caption or subtitles.” It is formed simply by adding -ing; no consonant is doubled. As a noun, it emphasizes the process or system rather than one individual caption. Picture someone preparing text so that viewers can follow a silent video or understand an online lecture. Useful combinations include accurate captioning, closed captioning, automatic captioning, and captioning for videos. Unlike translation, captioning may reproduce speech and important sounds in the same language.

captioning の語源・成り立ち Etymology
ラテン語 captio（捕らえること）が語源で、動詞 capere（つかむ・取る）から派生。元は文書の「見出し＝読者の注意を捕らえるもの」の意。関連語に capture（捕獲）や captive（捕虜）がある。
Captioning is the -ing form of caption. Caption ultimately developed from Latin captio, “a taking or seizing,” from capere, “to take.” The word came to denote a heading that catches attention and later a descriptive line attached to an image. With the development of film, television, and digital media, caption also became a verb meaning “to supply with captions or subtitles,” from which the process noun captioning was formed.
