sorrowing

The core word 'sorrow' originates from the Old English 'sorg', which denoted grief, regret, trouble, or care. This term has deep Germanic roots, stemming from the Proto-Germanic 'surgō', and is further linked to the Proto-Indo-European 'swergh-', meaning 'to worry, be sick'. The addition of the '-ing' suffix, from Old English '-ende' (present participle) and '-ung' (noun suffix), creates a form that describes the state or action of experiencing this profound sadness. Thus, 'sorrowing' directly channels this ancient sense of mental anguish into a word describing the active or continuous state of grief.

The word 'sorrowing' is a present participle or adjective formed from the base word 'sorrow'. 'Sorrow' is a simplex word of Old English origin, and the suffix '-ing' is added to form the participle/adjective. Therefore, it is not segmentable into meaningful, independent morphemes based on the current spelling.
