Etymology

puerile = puer<child> + ile<adjective suffix>

  • puer (from Latin puer): means "child" or "boy."
  • ile (from Latin -ilis): a suffix forming adjectives, often implying "pertaining to" or "characteristic of."

Etymology Origin:
The word puerile traces back to Latin puerilis, derived from puer (child). It entered English in the late 16th century, originally describing qualities associated with childhood. Over time, it acquired a pejorative sense, emphasizing immaturity or triviality. The suffix -ile is common in Latin-derived adjectives (e.g., juvenile, fragile), reinforcing the word’s descriptive nature.
