Etymology

ostensibly = ostens<show> + ibly<adverb suffix>

  • ostens (from Latin ostendere, meaning "to show" or "display")
  • ibly (adverbial suffix derived from Latin -ibilis, indicating capability or manner)

Etymology Origin:
The word ostensibly originates from the Latin ostendere ("to show"), which evolved into the Late Latin ostensibilis ("capable of being shown"). Over time, it entered Middle French as ostensible (meaning "apparent") and was later adopted into English in the 18th century. The adverb form ostensibly retains the core idea of something being presented or shown outwardly, often with an implied contrast to hidden truth.
