sorrowful

The word 'sorrowful' is a transparent English compound built from native Germanic elements. Its core, 'sorrow', descends from the Old English noun sorg, which denoted grief, care, or anxiety, a concept with deep Proto-Germanic roots. The adjectival suffix '-ful', from Old English -ful, literally means "full of," directly attaching to nouns to create descriptive qualities. Therefore, the literal construction "full of sorrow" has remained semantically stable for centuries, cleanly mapping the ancient morphemic logic onto the modern abstract sense of profound sadness.
