La palabra del día: Allanar

Verb. From llano, flat, to make something flat, to smooth.
In Legal Spanish allanar means nothing like the above but to search a property with a court order. The noun is orden de allanamiento. Curiously, allanamiento de morada is a crime: home invasion.
Another twist, the verb allanarse a (reflective) means to accept, to conform, to settle and agree to something. In Legal Spanish is used in the expression allanarse a la demanda, when the demandado accepts the claim made by the demandante. dc
