An individual with Sun conjunct Mercury combines will-power, overall outlook on life and the centrality of their being, with speech, communicating, and language all into an intense and focused expression. Since the Sun and Mercury are never more than 28 degrees apart, this aspect is fairly common. However, it makes it no less potent. If the Sun and Mercury are in different signs it is, however, thought to give more objectivity.
This is often an extremely creative combination associated with all forms of mental achievement and it can especially incline an individual to be in the limelight or find some recognition in the area of communication. Perhaps it is most expressed through the individual gaining knowledge, traveling or achieving a distinction in scholastic or literary areas. To assist in these matters, the mind can be active and the person takes pride in making good use of it. The intellectual talents and capabilities shine, and they speak with passion and warmth. Furthermore, it can sometimes make the Sun conjunct Mercury person disposed to live in the head.

As with all Mercurial contacts, it gives an inclination towards writing, lecturing or debating. The wit, humor, and cleverness exuded will ensure there is a good response from others.

The individual might be prone to over-rationalization, and sharpness of mind. With the Sun conjunct Mercury, they can be the beacon of light within the communication area. With this conjunction, however, it can often mean the self-image and mental expression are tightly bound together. Some astrologers imply that such an individual will have difficulty in seeing outside of their own opinions, ideas, and thinking. It can be associated with serious ‘blindspots’ resulting from a strength of ideas. All people have subjectivity but it may be harder for Sun-Mercury to separate from their personal views, and it can make taking in the views of others difficult.

However, Margaret Hone and plenty of modern astrologers disagree with this statement. On the whole, the mind it thought to be energized, alert and lively. On the positive side, it can make them an effective communicator, with a talent for influencing others with the power of their words.
