What is "Sun conjunct Mercury"?

The literal astrological meaning of Sun conjunct Mercury is that the Sun and Mercury are within 10 degrees of each other in a birth chart. The conjunction is the strongest when the Sun and Mercury are at the same degree, and they amplify one another's astrological energies.

People born with the Sun-Mercury conjunction possess mental energy and can apply logic and definition to will, resulting in high intelligence and communication abilities in which they find pride. Opinionated, animated speakers and independent thinkers, Sun-conjunct-Mercury people have difficulty listening to others' opinions and feel slighted if their opinions go unheard or are criticized.
