albear

A regional and fairly literary verb with two separate senses: in Andalusia and the Canary Islands, it means to whitewash walls with lime (albear las paredes); elsewhere it can mean simply to show white, or for the sky to begin turning pale at first light. Not a verb most learners will need actively, but worth recognizing in regional or older texts.

• Cada primavera, albeaban las paredes del cortijo. — Every spring, they'd whitewash the farmhouse walls.
• El horizonte empezaba a albear antes del amanecer. — The horizon was starting to turn pale before dawn.
• Las casas albeadas destacaban contra el cielo azul. — The whitewashed houses stood out against the blue sky.

Assuming albear is a general synonym for pintar (to paint) — it specifically means whitewashing with lime, a rural building technique, not painting with any color or material.
