This relates to the meaning of "spire" as a tall, pointed structure, often found on top of buildings or towers. The spiraling form of the spire can be thought of as a coil or twist reaching upwards.
Here are some examples of how "spire" is used in words:
* Aspire: To have a strong desire to achieve something. The "sp" in aspire comes from the same root as "spire," suggesting a reaching upwards towards a goal.
* Conspire: To plan together secretly, usually to do something harmful or illegal. The "sp" in conspire also comes from the same root as "spire," suggesting a twisting or winding together of plans.
* Respiration: The process of breathing. This word directly derives from the Latin "spira," emphasizing the act of breathing in and out.
So, while the word "spire" itself primarily refers to the physical structure, its root meaning highlights the upward-reaching, spiraling, or breathing aspects of things.
