'V-formation' originates from the shape of the letter 'V' and the word 'formation,' which comes from Latin 'formatio,' meaning 'a shaping.'

'Formation' changed from the Latin word 'formatio' and eventually became the modern English word 'formation.'

Initially, 'formation' meant 'a shaping or arranging,' and over time it evolved to include specific arrangements like the 'V-formation' used by birds.
