What Does “Erection” Mean?

“Erection” has more than one meaning.

In a medical or biological context, an erection refers to the state in which the penis becomes firm, usually because of increased blood flow. Words such as penile rigidity, firmness, and tumescence may be used in more formal or clinical writing.

In a construction context, erection means the process of assembling or putting up a structure. For example, “the erection of the steel frame” means the process of constructing or assembling it.

Therefore, the best synonym depends on what you mean.
