Etymology
The word is a transparent English compound formed in the modern era. The first element, "mid," derives from the Proto-Germanic midja-, meaning "middle," a concept with deep Proto-Indo-European roots in médhyos. The second element, "fifties," originates from Old English fīftig, itself from the Germanic base of "five." The compound logically combines these elements to denote the central portion of a specified decade, whether applied to an individual's age or a historical period. Its formation follows a common English pattern for creating precise temporal references, such as "mid-thirties" or "late-eighties."
Analysis
Structure: mid (middle) + fifties (the decade from 50 to 59)
- mid: From Old English midd (middle, central). In this compound, it functions as a combining form meaning "the middle part of."
- fifties: From Old English fīftig (fifty). The "-ties" suffix forms the plural noun denoting a decade of years (e.g., the 50s). Here, it specifies the particular decade being referenced.
