Mercury in Sagittarius traits

Big-picture, honest and enthusiastic, Mercury in Sagittarius is read as a mind that loves meaning more than detail. Tradition calls this Mercury's detriment, the sign opposite Gemini, which is usually read as thinking that's broad and visionary rather than precise. People with Mercury in Sagittarius tend to be curious about philosophy, travel, cultures and big ideas. They're frank, funny and inspiring teachers. The blind spot is bluntness and overlooking the details: they may promise more than they can deliver or say something tactless while trying to be honest. A friend who checks the fine print is a gift to them. They often collect books, passport stamps and big questions, and they love a long conversation that ends somewhere unexpected. Their optimism lifts people up, and their storytelling makes ordinary events sound like adventures. They tend to learn best through experience and travel rather than rote study.
