verb

clavar

nail

Introducir algo puntiagudo en una superficie usando fuerza.

Clavar primarily means to drive or hammer something into a surface, especially a nail. It can also mean:

To stab or stick something into something: driving a sharp object into a surface or body.
To fix or fasten: attaching something firmly, often with nails.
To fix one’s gaze: staring intently at someone or something.
To nail something figuratively: doing something exactly right.
To overcharge someone: colloquially, charging an excessively high price.

Clavar is a regular -ar verb. Its reflexive form, clavarse , can mean “to become stuck” or “to stick oneself.”

It comes from Latin clavāre, meaning “to fasten with nails,” from clāvus, “nail.”

hincar — to drive or thrust something in; often emphasizes penetration rather than fastening.
fijar — to fix or secure something; broader and does not necessarily involve nails.
acertar — to get something right; a synonym for the figurative sense, though clavar often suggests particular precision.
desclavar — to pull out a nail or remove something that has been nailed down; an antonym of the fastening sense.
