  We have studied charged current neutrino/antineutrino induced weak pion
production from nucleon. For the present study, contributions from
$\Delta(1232)$-resonant term, non-resonant background terms as well as
contribution from higher resonances viz. $P_{11}$(1440), $D_{13}$(1520),
$S_{11}$(1535), $S_{11}$(1650) and $P_{13}$(1720) are taken. To write the
hadronic current for the non-resonant background terms, a microscopic approach
based on SU(2) non-linear sigma model has been used. The vector form factors
for the resonances are obtained from the helicity amplitudes provided by MAID.
Axial coupling in the case of $\Delta(1232)$ resonance is obtained by fitting
the ANL and BNL $\nu$-deuteron reanalyzed scattering data. The results of the
cross sections are presented and discussed for all the possible channels of
single pion production induced by charged current interaction.
