caret
Synonym discussion
Sense: noun/2
In computing, a caret is the blinking vertical line that marks where typed text will appear. The word cursor is broader — it can mean any on-screen position indicator, including the mouse arrow. The insertion point is the precise technical term used in word-processing software menus and dialogs, though it rarely appears in everyday conversation. A text cursor is simply a more descriptive synonym that distinguishes the blinking line from the mouse cursor. In practice, most people say 'cursor' in casual speech and rely on context to clarify which kind they mean.
Etymology
From Latin caret, meaning 'it is lacking' or 'there is wanting' — the third-person singular present indicative of carēre, 'to lack, be without.' Printers and editors adopted the word as a proofreading mark in the 17th century to signal missing text that needed to be inserted.
