culebrear

To move sinuously in S-shaped curves, like a snake (culebra) — used of a river, road, line of people, or vehicle, and figuratively of an argument or idea that winds and evolves indirectly. Regionally (Guatemala, Honduras, El Salvador) it can mean to flatter servilely; in the Dominican Republic and Puerto Rico, to dodge a responsibility with excuses.

• El río culebrea entre las montañas. — The river winds between the mountains.
• El coche culebreaba por la carretera de montaña. — The car snaked along the mountain road.
• Su argumento culebreaba sin llegar a ningún punto claro. — His argument meandered without reaching any clear point.

Learners often reach for serpentear, its close synonym — both work for physical winding, but culebrear's figurative and regional senses (flattery, evasion) don't carry over to serpentear.
