terpri

/ter'pree/ [from LISP 1.5 (and later, MacLISP)] vi. To output a newline. Now rare as jargon, though still used as techspeak in Common LISP. It is a contraction of `TERminate PRInt line', named for the fact that, on some early OSes and hardware, no characters would be printed until a complete line was formed, so this operation terminated the line and emitted the output.
