Description
BESIII has now collected the world's largest $e^+e^-$ annihilation samples
taken at $E_{cm} = 4.009$ and $4.178$ GeV, which contain copious charmed-strange mesons.
In this talk, I report our recent studies on leptonic and semileptonic
decays of the $D_s$ meson, which allow us to extract the CKM matrix elements $|V_{cs(d)}|$ and
the decay constants $f_{D_s^+}$ or semileptonic form factors.
Our recent preliminary results on $D_s$ hadronic decays are also presented,
including $D_s^+ \to p \bar{n}$.
