Scientific paper

I describe CLEO-c purely leptonic decay results leading to fD+=(222.6 +/-
16.7^{+2.8}_{-3.4}) MeV, fDs+=(280.1 +/- 11.6 +/- 6.0) MeV, and fDs+/fD+=1.26
+/- 0.11 +/-0.03. Form-factor measurements in Cabibbo favored and suppressed
pseudoscalar decays are presented. Some comparisons are made with theoretical
predictions.
