How this placement behaves
In classical astrology, Mercury signifies intellect, commerce, translation, craft. When Mercury is placed in Virgo, those significations are refracted through the maiden. virgo refines, separates, and perfects. it is orderly, analytic, and attentive to service, craft, and bodily maintenance.
Mercury is in domicile here, which changes the quality of its expression before any aspect or accidental condition is considered.
