Air Signs

Aquarius, Gemini and Libra — the three signs of ideas, communication and connection.

Air signs are traditionally read as the zodiac’s communicators: curious, social, and most alive when trading ideas. The temperament is intellect rather than spirit or matter — air signs tend to process a feeling by talking or thinking it through rather than sitting with it.

The air signs

Aquarius, Gemini and Libra share the air element. Signs of the same element are traditionally read as sharing a basic temperament — the way they take in and give out energy — even where the rest of the chart differs.

How modality splits the air signs

Element describes temperament; modality describes how a sign meets change. The three air signs each carry a different modality, so no two of them express air the same way.

Traditional compatibility

Fire and air signs are traditionally described as energetically compatible with each other, which puts the air signs alongside the fire signs. Treat this as a starting heuristic rather than a rule — a whole chart has far more to say about two people than their sun signs do.

The other elements

Every sign belongs to one of four elements. See how air compares to the rest.
