  We extend the warm inflationary scenario to the case of the noncanonical
scalar fields. The equation of motion and the other basic equations of this new
scenario are obtained. The Hubble damped term is enhanced in noncanonical
inflation. A linear stability analysis is performed to give the proper
slow-roll conditions in warm noncanonical inflation. We study the density
fluctuations in the new picture and obtain an approximate analytic expression
of the power spectrum. The energy scale at the horizon crossing is depressed by
both noncanonical effect and thermal effect, and so is the tensor-to-scalar
ratio. Besides the synergy, the noncanonical effect and the thermal effect are
competing in the case of the warm noncanonical inflation.
