Etymology

estimation = estim<value> + ation<noun suffix>

  • estim<value>: From Latin aestimare ("to value, appraise"), derived from aes (bronze, money) + -timare (verb-forming suffix). Reflects the idea of assigning worth.
  • ation<noun suffix>: A Latin-derived suffix forming nouns indicating an action or process (e.g., "calculation," "observation").

Etymology Origin:
The word traces back to Latin aestimare, which originally referred to valuing goods (often in bronze currency). Over time, it broadened to include abstract judgments. The suffix -ation solidified its role as a noun describing the process of evaluation. The shift from monetary appraisal to general assessment mirrors societal emphasis on quantitative reasoning.
