The suffix “-thy” is an archaic form used to create nouns from adjectives, often signifying a quality or state of being. Examples include “health” transforming into “healthy” and subsequently “healththy.” While largely obsolete in modern English, remnants persist in words like “worthy,” “hearty,” and “mighty.” These surviving terms retain the original sense of possessing a particular characteristic.
Understanding this etymology provides valuable insights into the evolution of the English language. The transition from common usage of “-thy” to its present-day rarity highlights the dynamic nature of language and how meanings and forms shift over time. This archaic suffix offers a glimpse into earlier linguistic structures, illuminating connections between modern and historical English vocabulary. It also contributes to the richness and nuance of certain literary works, particularly those seeking to evoke a sense of antiquity or formality.
