What the 3rd house covers
This is the house of the local and the daily: the messages you send, the errands you run, the way you learned in school and the people you grew up next to. It describes how you gather and pass on information.
It is Mercury's natural territory, so it says a lot about the style of your thinking, especially when Mercury itself sits here.
Planets in the 3rd house
Mercury here makes a natural communicator. Mars here makes a sharp debater. The Moon here ties feelings to conversation and siblings. Saturn here can describe early learning that felt hard and later becomes expertise.
An empty 3rd house
With no planets here, read the sign on the cusp for your communication style and the house its ruler occupies for where your conversations tend to go.
A worked example
Gemini on the 3rd house cusp with Mercury in the 9th: a mind that starts with everyday questions and keeps widening them into big ones.
