  Non-Gaussianity generated in inflation can be contributed by two parts. The
first part, denoted by $f_{NL}^{\delta N}$, is the contribution from four-point
correlation of inflaton field which can be calculated using $\delta N$
formalism, and the second part, denoted by $f_{NL}^{int}$, is the contribution
from the three-point correlation function of the inflaton field. We consider
the two contributions to the non-Gaussianity in noncanonical warm inflation
throughout (noncanonical warm inflation is a new inflationary model which is
proposed in \cite{Zhang2014}). We find the two contributions are complementary
to each other. The four-point correlation contribution to the non-Gaussianity
is overwhelmed by the three-point one in strong noncanonical limit, while the
conclusion is opposite in the canonical case. We also discuss the influence of
the field redefinition, thermal dissipative effect and noncanonical effect to
the non-Gaussianity in noncanonical warm inflation.
