The adjective "significant" finds its origins in the Latin present participle "significantem," derived from the verb "significāre," which means "to signify," "to indicate," "to mean," or "to portend." This Latin verb itself is a compound formed from two distinct roots: "signum," meaning "a mark," "sign," or "token," and "facere," meaning "to make" or "to do." The combination of these elements yields a literal sense of "making a sign" or "producing a mark," which metaphorically extends to the notion of indicating or conveying meaning.
The root "signum" is inherited from Latin and is generally believed to trace back to the Proto-Indo-European (PIE) root *sekʷ-, which carries the sense "to follow." This connection is somewhat speculative but widely accepted among historical linguists, as the concept of a "sign" can be understood as something to be followed or observed. On the other hand, "facere" is a well-attested Latin verb inherited from the PIE root *dʰeh₁-, meaning "to set," "to put," or "to make." This root is the source of numerous derivatives across Indo-European languages that involve the
The compound verb "significāre" thus encapsulates the act of "making a sign" or "indicating," which in Roman culture carried both practical and symbolic weight. Beyond its general meaning of "to mean" or "to indicate," "significāre" also bore a specialized divinatory sense: it could mean "to portend" or "to be an omen." This reflects the Roman practice of interpreting natural phenomena or events as signs from the divine, a cultural context that imbued the term with a sense of importance and portentousness.
From "significāre," the present participle "significantem" entered Late Latin and subsequently evolved into the adjective "significant" in English by the 16th century. The English adoption retained the core meanings of being "sufficiently great or important to be worthy of attention" and "having a particular meaning or indication." The word thus preserved the dual sense of marking something as noteworthy and conveying meaning.
In English, "significant" is part of a family of related words derived from the same Latin root, including "signify," "significance," "insignificant," and "signification." These derivatives share the semantic field of meaning, indication, and importance, reflecting their common etymological heritage.
A notable development in the semantic history of "significant" occurred in the early 20th century, particularly in the 1920s, when the term acquired a precise technical meaning in the field of statistics. The British statistician Ronald Fisher formalized the concept of "statistical significance," using "significant" to denote a result unlikely to have occurred by chance alone. This mathematical and scientific usage added a layer of exactitude to the previously general term, which had been used more loosely to indicate importance or meaningfulness.
In summary, "significant" is a word deeply rooted in Latin, formed from the combination of "signum" (a mark or sign) and "facere" (to make or do), reflecting the idea of "making a sign" or "indicating." Its inherited components trace back to Proto-Indo-European roots *sekʷ- and *dʰeh₁-, though the precise semantic pathways involve some uncertainty. The term's evolution from a general sense of indicating or portending in Roman times to its modern English usage encompasses both everyday and specialized scientific meanings, illustrating the dynamic interplay between language, culture, and knowledge.
