destajar

The verb behind the far more common phrase a destajo (piecework, paid by output rather than by hours) and hablar a destajo (to talk nonstop). As a standalone verb, destajar is archaic/rare, historically meaning to cut short or interrupt; almost no modern speaker uses it outside these fixed expressions.

• Los obreros trabajaban a destajo, cobrando por pieza terminada. — The workers were paid by the piece, earning per finished item.
• Habla a destajo y no deja hablar a nadie más. — He talks nonstop and doesn't let anyone else speak.
• El sistema de pago a destajo motivaba mayor producción. — The piecework payment system encouraged higher output.

Trying to conjugate destajar freely in modern sentences — a native speaker would almost always reach for the fixed noun phrase a destajo instead of the bare verb, which reads as archaic or stilted today.
