dearly

The adverb 'dearly' is formed directly from the adjective 'dear', which originates from the Old English 'dēore', meaning precious, costly, or beloved. This Old English term is traced back to the Proto-Germanic 'diurijaz', carrying the same dual sense of high value and emotional esteem. The suffix '-ly', from Old English '-līce', is a standard Germanic adverbial formative. Thus, 'dearly' logically inherits the adjective's two primary connotations, describing actions done with deep affection or acquired at a significant price, preserving the ancient link between economic and emotional value.
