gratuitously

The word 'gratuitously' originates from the Latin adjective gratuitus, meaning 'given freely' or 'spontaneous', which itself is derived from gratus ('pleasing, thankful'). The core concept of being 'given without payment' evolved logically into the sense of being 'uncalled for' or 'without cause', as something given freely can be perceived as unnecessary or unwarranted. The suffix -ous was added to form the adjective 'gratuitous', meaning 'uncalled for' or 'free of charge'. Finally, the adverbial suffix -ly, of Germanic origin, was appended to create the modern adverb, describing an action performed in an unjustified or unnecessary manner.
