It might seem surprising, but "build" has a long history and evolved from the Old English word "byldan", meaning "to make, to form, to create". This word, in turn, is derived from the Proto-Germanic word "bold-", which meant "to build, to make".
The connection to "bold" comes from the Proto-Germanic word *balþaz, which meant "strong, powerful, brave". This suggests that the original concept of building was related to creating something strong and enduring.
Interestingly, this connection is still reflected in some modern English usage. For example, we might say that someone is "built like a brick house" to describe their strength and physical stature.
