Meaning changes in pronominal verbs

Changing meaning with pronouns

In Spanish, adding a reflexive pronoun (me, te, se, etc.) to a verb doesn't always just mean doing the action to yourself. Often, it completely shifts the verb's definition.

Let's look at how this works in the high-stakes world of undercover operations, starting with jugar (to play) and jugarse (to risk or put on the line):

The infiltrator plays chess, but today he is risking his life.
El infiltrado juega ajedrez, pero hoy se juega la vida.

Aprovechar vs. aprovecharse de

Aprovechar means to make the most of something positive, like time or an opportunity. Add a pronoun and the preposition de, and aprovecharse de takes on a negative meaning—to take advantage of someone:

We make the most of the time, but that agent takes advantage of people.
Nosotros aprovechamos el tiempo, pero ese agente se aprovecha de la gente.

Negar vs. negarse a

Negar simply means to deny a fact or an accusation. By making it pronominal and adding the preposition a, negarse a means "to refuse to" do something:

The spy denies the plan and refuses to collaborate.
El espía niega el plan y se niega a colaborar.

Despedir vs. despedirse de

A boss can fire someone from a job (despedir), but an agent who leaves quietly might not say goodbye to anyone (despedirse de):

Interestingly, the boss fires him and he does not say goodbye to anyone.
Curiosamente, el jefe lo despide y él no se despide de nadie.

Pasar vs. pasarse

Pasar is a versatile verb meaning to pass, happen, or go (as in going unnoticed). But when a spy crosses the line or pushes things too far, the verb becomes pasarse:

The spy goes unnoticed, but today he goes too far.
El espía pasa desapercibido, pero hoy se pasa.
