"Turn" is derived from the Old English word "tyrnan," meaning "to twist, to revolve." This word itself has roots in the Proto-Germanic word "*turnaną*," which likely originated from the Proto-Indo-European "*ter-/*tern-," meaning "to rub, to grind, to turn."
"To" is an extremely old word, originating from the Proto-Indo-European "*tu," meaning "to, towards." It's found in almost all branches of the Indo-European language family.
When combined, "turn to" originally meant "to direct oneself towards something or someone." This meaning is still present in phrases like "turn to the left" or "turn to the next page," where it signifies physical direction.
However, over time, the phrase developed more metaphorical and abstract meanings. "Turn to" now often signifies:
* Seeking help or guidance: This meaning arises from the idea of "turning to" someone for support, as in "turn to your friends for help."
* Changing one's focus or attention: As in "turn to the next task" or "turn to a new chapter in life."
* Resorting to a particular action or method: Like "turn to violence" or "turn to a new strategy."
The phrase "turn to" is therefore a testament to the evolution of language, where simple words combine to form expressions with nuanced meanings.
