Etymology

species = spec<look> + ies<noun suffix>

  • spec (from Latin specere, meaning "to look" or "observe")
  • ies (a Latin-derived noun suffix indicating plural or collective form)

Etymology Origin:
The word species originates from Latin species, meaning "appearance, form, or kind," derived from specere ("to look"). It originally referred to visual classification—how things appear or are grouped based on observable traits. Over time, its meaning narrowed in biology to denote groups of organisms sharing genetic and reproductive traits. The suffix -ies preserves the Latin plural form, reflecting its scholarly adoption into English.
