Per aspera ad astra

Meaning and grammar

The construction uses the preposition "per" (through) with "aspera," the neuter plural noun meaning "rough things" or "hardships," and the directional phrase "ad astra" (to the stars). Word order in Latin is relatively flexible, so variants such as ad astra per aspera convey the same sense. English translations vary slightly: "through difficulties to the stars," "to the stars by hardships," or the simpler idiom "to the stars through adversity." Linguistic notes discuss these forms in more detail.

Origins and classical echoes
