Consequence and purpose connectors (de modo que, de manera que)

Consequence vs. Purpose

Both de modo que and de manera que translate to "so" or "so that." The verb mood you use after them depends on whether you are talking about a real result (a consequence) or an intended goal (a purpose).

Using the Indicative for Consequences

If you are stating an actual result—a fact or something that is currently happening—use the indicative mood. In this context, the connectors mean "so" or "as a result."

I adjust the screen, so it is comfortable for my eyes.
Ajusto la pantalla, de modo que es cómoda para mis ojos.
He places an ergonomic support, so his back is straight.
Él coloca un soporte ergonómico, de manera que su espalda está recta.

Using the Subjunctive for Purpose

If you are talking about the intended purpose behind an action, use the subjunctive mood. Because the outcome is a goal rather than a guaranteed reality, the subjunctive is required. Here, the connectors mean "so that" or "in order to."

I raise the screen so that my back does not hurt.
Yo elevo la pantalla de modo que no me duela la espalda.
I place the mice here so that you do not have tension.
Coloco los ratones aquí de manera que ustedes no tengan tensión.
