Playpen

Part of speech: noun

Definitions

1. A confined space intended for toddlers to engage in play without risk of injury or straying beyond its boundaries
2. An enclosed area that provides a secure environment for young children to explore and enjoy recreational activities safely
3. A designated area with protective barriers where small children can safely engage in play while being supervised

Etymology: "Pen" here is the old sense of an enclosure for animals, the same word that gives us "pen" for a sheep fold or a writing instrument's ink reservoir (a homonym with a separate history). "Play" is the ordinary verb and noun from Old English, meaning to amuse oneself or take part in a game. Put together, a playpen is simply a pen for play: a small fenced enclosure where a child can be kept safe while being watched. The compound is a plain, transparent formation rather than a coinage with a famous backstory. Its meaning follows directly from its two parts, and the word reads as a literal description of its use, with no figurative drift between the parts and the whole.

Synonyms: crib, play yard, play area
