thoroughly = thorough<complete> + ly<adverb suffix>
- thorough: Derived from Old English thurh (through), later influenced by Middle English thorow, meaning "complete" or "exhaustive." The modern sense emphasizes attentiveness to detail.
- ly: A common English adverb-forming suffix, originating from Old English -līce, indicating manner or degree.
Etymology Origin:
The word thoroughly evolved from the Old English concept of "going through" (thurh) to its Middle English form thorow, which acquired the meaning of "complete" by the 16th century. The addition of -ly standardized its adverbial function, reflecting meticulousness. The spelling shift to thorough in Modern English solidified its link to comprehensiveness.
