Infra vs. Supra — What's the Difference?

Difference Between Infra and Supra


Key Differences

Infra is used to refer to a part of the body that is located below another, like the inframammary fold which is beneath the breast. Supra, on the other hand, is utilized to describe parts situated above others, as in supraorbital which refers to being above the eye socket.
Infra can refer to content that will be discussed later in a document, like "see infra for more details". Supra, conversely, references previously discussed content, with phrasings like "as mentioned supra".
In architectural and construction lingo, these words retain their spatial connotations.
Infra denotes elements or sections located below a specific point of reference, for instance, infrastructure, which lays the foundation of any construction. Supra is used to describe components that are situated on the upper side, like a supralateral arch.
