aguisar

An archaic verb from medieval Spanish meaning to prepare or arrange something, especially food or provisions — found in texts like the Cantar de Mio Cid and the works of Gonzalo de Berceo. Long obsolete in modern Spanish, where preparar or aderezar took over entirely.

• En el cantar, los criados aguisan la cena para el Cid. — In the epic poem, the servants prepare dinner for the Cid.
• El texto medieval describe cómo se aguisaba la comida del viaje. — The medieval text describes how the food for the journey was prepared.
• Aguisar las vituallas era tarea de los sirvientes. — Preparing the provisions was the servants' job.

Expecting any modern speaker to recognize or use aguisar — it's a dead word outside medieval-literature study; using it in ordinary writing will simply read as a typo or archaism, not a stylistic choice most readers catch.
