Sun
The Sun is the core of a chart — the sense of self a person is working out over a lifetime. Your sun sign describes what you are fundamentally about, and what you are here to become more fully.

In Your Chart
The Sun's house shows where you most want to shine and where recognition matters to you. A well-expressed Sun feels like being yourself without apology.

What The Sun Describes
The Sun is identity and direction - not what somebody is like on a Tuesday, but what they are organised around and moving toward. It is the closest thing in a chart to a statement of purpose, and it is the placement most people already know because it is the only one a birth date settles on its own.
That last fact is the reason for most of the confusion about it. The Sun became the popular placement for a practical reason rather than an astrological one: it is the only one you can calculate without knowing what time somebody was born. It was never intended to carry the entire reading.
The traditional framing is worth keeping: the Sun describes what a person is becoming rather than what they currently are. This explains the common experience of a sun sign description fitting better at forty than at twenty. A trajectory is easier to recognise once some of it has been travelled.
The Sun By House
The sign describes the style; the house describes where it gets spent. A Leo Sun in the tenth house is somebody whose identity is bound up with public standing and visible work. The same Leo Sun in the fourth is somebody whose warmth and authority operate primarily inside a family.
This is why two people with the same sun sign can be genuinely unalike, and why house placement is a better predictor of what somebody actually does with their day than the sign is.
Common Misreadings
The most frequent error is treating the Sun as the whole person. It is one placement of ten, and a chart where the Moon and ascendant point elsewhere will produce somebody who does not recognise their sun sign description at all.
The second is reading the Sun as a fixed character rather than a direction. Somebody with a Capricorn Sun is not necessarily disciplined - they are somebody for whom discipline and structure are the material they are working with, including by struggling with it.
The third is confusing the Sun with the ego in a pejorative sense. In chart terms it is closer to the organising principle: the thing other placements are arranged around.
