Falso vs. incorrecto
While both falso and incorrecto can translate to false or incorrect in English, they are not always interchangeable. The key difference lies in the nuance: falso often implies deceit or a lack of authenticity, while incorrecto typically refers to a mistake, an error, or something that doesn't follow established rules.
Falso
A2This word means false, fake, counterfeit, or insincere. It is the direct opposite of verdadero (true) and often implies that something is deliberately untrue or not genuine.

Incorrecto
A2This word means incorrect, wrong, or improper. It is the direct opposite of correcto (correct) and usually points to an error, a mistake, or a violation of rules or standards, without necessarily implying deceit.

Summary
In essence, use falso when describing something that is deliberately untrue, counterfeit, or not genuine (a falso friend, a falso diamond). Use incorrecto for mistakes, errors, or actions that are not proper (an incorrecto calculation, an incorrecto behavior). A statement can be described as both, but falso leans towards a lie, while incorrecto leans towards a simple error.
