'aggressively-gathered' originates from the combination of 'aggressively' and 'gathered', where 'aggressively' is derived from Latin 'aggressivus', meaning 'attack', and 'gathered' from Old English 'gadrian', meaning 'to bring together'.

'aggressively-gathered' changed from the combination of 'aggressively' and 'gathered' in modern English to describe a forceful method of collection.

Initially, 'aggressively' meant 'in an attacking manner', and 'gathered' meant 'collected'. Over time, the combination evolved to describe a forceful method of collection.
