What does Sun in the 3rd house mean?
The 3rd house is traditionally associated with learning, communication, siblings, short journeys and everyday exchange. With the Sun here, astrologers often emphasize becoming more fully oneself through ideas and conversation.
How can this placement express itself?
This can be read as a strong drive to understand, explain, ask questions or be heard. Writing, teaching, speaking and active curiosity may become important arenas for self-expression.
What should you watch for?
The shadow can be talking to prove intelligence, scattering attention or confusing having an opinion with having examined an issue. The broader chart matters for how communication actually functions.
A useful reflection question

Why birth time matters
House placement depends on the birth time, place and house system. If your birth time is uncertain, your Sun house can change even though your Sun sign stays the same. Compare charts using the same settings and keep uncertainty visible.
