Etymology

ostensible = ostens<appear> + ible<capable of>

  • ostens (from Latin ostendere, meaning "to show" or "appear")
  • ible (Latin suffix -ibilis, indicating capability or tendency)

Etymology Origin:
Derived from Latin ostendere ("to show"), ostensible entered English via French in the 18th century. The root ostens- reflects outward appearance, while -ible suggests a passive quality—hence, "capable of being shown" or "apparent." Over time, it acquired a connotation of superficiality, implying a discrepancy between appearance and reality.
