'trendily-done' originates from the English word 'trendy,' which comes from the word 'trend,' meaning 'a general direction in which something is developing or changing.'

'trendy' evolved from the word 'trend' in the 20th century, and 'trendily-done' is a modern adaptation to describe something done in a trendy manner.

Initially, 'trend' referred to a general direction, but 'trendily-done' now specifically refers to actions or items completed in a fashionable way.
