tailend

Tailend is a term used to denote the far end or last part of something, especially the rear portion or trailing segment. In general use it describes the portion farthest from the front or leading edge, and it can be employed metaphorically to refer to the concluding stage of a process or sequence. The two-word form tail end is more common in everyday English, while tailend appears mainly in specialized or compound terms.

Biology and anatomy: In animals, the tail end refers to the hind region near the tail; in humans, it can evoke the coccyx or the overall posterior portion of the body. In zoological and anatomical writing, more formal terms such as caudal or posterior are often used, but tail end remains common in casual description.

Astronomy and space: The tail end can describe the farthest portion of a comet’s tail as it trails away from the nucleus, or more generally the trailing region of any feature in space. The concept emphasizes distance from the source rather than intrinsic structure.

Media, computing, and data: In broadcasting or publishing, the tail end denotes the final segment of a program, article, or sequence. In computing, tail end can refer to the trailing portion of a data stream, file, or string. The Unix tail command, which outputs the last lines of a file, is a well-known practical reference in technical contexts.

Notes: The term is versatile across disciplines and is typically understood from context. While tail end is common in the two-word form, tailend may appear in specialized compound terms or brand names.
