regularly

The word "regularly" is built upon the Latin root reg-, meaning "to rule, guide, or keep straight," which itself derives from the Proto-Indo-European root h₃reǵ- meaning "to move in a straight line." This root gave rise to concepts of kingship (rex), direction (regula a ruler), and correct procedure. The suffix -ularis was added to form the Latin adjective regularis, meaning "according to rule." This passed into English as "regular." Finally, the native English adverbial suffix -ly was appended, creating "regularly" to describe an action performed in a manner that follows a rule, pattern, or consistent order. Thus, the word's journey from a literal sense of straight-line motion to the modern abstract meaning of habitual or periodic occurrence is a clear example of semantic evolution from concrete governance to patterned behavior.
