Mercury in Sagittarius: What It Means

Mercury in Sagittarius thinks in big pictures. Details bore you. What matters is the meaning, the pattern, the philosophical implication. You can synthesize information from wildly different sources into a coherent worldview, but you sometimes sacrifice accuracy for scope.

Mercury is in detriment in Sagittarius, which means the planet of detail sits in the sign that is allergic to details. Your mind is excellent at big-picture synthesis and terrible at proofreading. You see forests clearly and step on individual trees without noticing.

In daily life, this looks like someone who says exactly what they think (sometimes before considering whether it needed to be said), who changes the subject to something more interesting mid-conversation, and who can connect any topic to a larger philosophical point. Tact is something you understand in theory but struggle with in practice.
