We study NLO QCD corrections as relevant to hadronic W decay in W pair
production at a future 500 GeV e(+)e(-) linac, with particular emphas
is on the determination of triple gauge boson vertices. We find that h
ard gluon bremsstrahlung may mimic signatures of anomalous triple gaug
e boson vertices in certain distributions. The size of these effects c
an strongly depend on the polarisation of the initial e(+)e(-) beams.
