prono

Prono is a term with multiple meanings across languages and fields. In Italian and other Romance languages, prono is an adjective meaning lying face down and describes a body position. The phrase in posizione prona is used in medical and sports contexts to indicate a prone posture, contrasting with in posizione supina (face up).

Medically, the root prono- denotes orientation toward the front or downward. The combining form prono- appears in terms describing movement or position, particularly in anatomy and biomechanics. For example, pronation refers to the rotation of the forearm or foot so that the palm or sole faces downward or inward.

Outside Romance-language usage, prono is not a standard English word and may be encountered mainly as a loanword, a proper name, or as an acronym (PRONO) in organizational titles or projects. Context is essential to determine its meaning.

Because the term is ambiguous, users should look for surrounding context to identify whether prono refers to a body position, a linguistic root, or an acronym.
