For if I measure anything by a yard, I know whether the thing I measure be longer or shorter than that supposed yard, though perhaps the yard I measure by be not exactly the standard:
Izan ere, zerbait yarda batez neurtzen badut, badakit neurtu dudan gauza yardatzat daukadan hori baino luzeago ala laburragoa den, neurtzeko erabili dudan yarda estandarrarekin justu-justu bat ez etorri arren, hau beste kontu bat delarik.
