The etymology of the word "peaky" can be traced back to Middle English. It is believed to derive from the Old Norse word "piki", which means "pointed" or "sharp". In Old English, "pice" was used to describe something sharp or pointed. Over time, this developed into the Middle English word "peaky", which originally meant "sharp-nosed" or "pinched in appearance". The term later gained associations with paleness, tiredness, or being unwell, which is the common usage seen today.
