The word "half turn" is a compound noun formed from two separate words.
1. "Half" comes from the Old English word "half", which means "one of two equal parts". It is also related to the Old Norse word "halfr" and the Dutch word "half", both with the same meaning. The word has remained relatively unchanged throughout its history.
2. "Turn" comes from the Old English word "tyrnan", which means "to rotate" or "to twist". It has cognates in other Germanic languages, such as Old High German "dornen" and Old Norse "thruma". Over time, it evolved into the Middle English word "turnen" and eventually into the modern English "turn".
When these two words are combined, "half" denotes the extent or degree, while "turn" specifies the action of rotating or twisting.
