  We derive a soft theorem for a massless scalar in an effective field theory
with generic field content using the geometry of field space. This result
extends the geometric soft theorem for scalar effective field theories by
allowing the massless scalar to couple to other scalars, fermions, and gauge
bosons. The soft theorem keeps its geometric form, but where the field-space
geometry now involves the full field content of the theory. As a bonus, we also
present novel double soft theorems with fermions, which mimic the geometric
structure of the double soft theorem for scalars.
