What does multiline mean?
Multiline describes text, an input field, or a display that occupies more than one line. It is especially common in computing, where a multiline text box lets users enter several lines without repeatedly activating a separate “new line” control, and where “multiline string” identifies text containing line breaks. The term is also useful in publishing, typography, signage, and form design, where it distinguishes a paragraph or block from a short single-line label. Multiline is not normally marked as slang and carries no strong positive or negative connotation. It is more precise than simply saying “long,” because its focus is on physical or digital arrangement: information is arranged across multiple rows rather than merely extending in length. The word combines the widely understood prefix multi-, meaning “many,” with line, the basic term for a row of written or printed material.

Where does multiline come from?
“Multiline” is a modern English compound formed from multi-, derived from Latin multus, meaning “many,” and line, which comes through Old French from Latin linea, originally associated with linen thread and later a written row. The compound developed as a descriptive term for text, displays, or input methods extending across several lines. Its etymological relatives include linear, alignment, and delineate, all ultimately connected with Latin linea.
