Etymology

solely = sole<alone> + ly<adverb suffix>

  • sole: From Latin solus (alone, single), entering English via Old French sol. Retains the core meaning of singularity or exclusivity.
  • ly: A productive Old English adverbial suffix derived from Germanic -līko, used to form adverbs from adjectives (e.g., "quickly," "happily").

Etymology Origin:
The word solely emerged in Middle English (14th century) by combining sole (emphasizing singularity) with the adverbial suffix -ly. Its development reflects a logical progression from the adjective sole ("alone") to the adverb solely ("exclusively"), preserving the original Latin root’s emphasis on isolation or uniqueness.
