Etymology

likely = like<similar> + ly<adjective/adverb suffix>

  • like: From Old English gelīc ("similar"), derived from Proto-Germanic galīkaz. Retains the core meaning of resemblance or probability.
  • ly: A productive suffix in Old English (-līc), used to form adjectives/adverbs indicating "having the quality of."

Etymology Origin:
The word likely originated in Old English as gelīclīc (literally "body-like"), combining gelīc ("similar") with the adjectival suffix -līc. Over time, gelīclīc simplified to likely, shifting from "having the appearance of" to expressing probability. The suffix -ly remains active in modern English (e.g., friendly, quickly), but likely uniquely bridges adjectival and adverbial roles.
