  We construct a global flat embedding structure of a Taub-NUT-AdS spacetime to
yield a (6+5)-dimensional novel global embedding Minkowski spacetime. We also
investigate Taub-NUT, Schwarzschild-AdS and Schwarzschild limits of the global
embedding by exploiting parameter reduction scheme. In particular, we observe
in the vanishing monopole strength limit of the Taub-NUT-AdS that the parameter
reduction is not smoothly applicable to the Schwarzschild-AdS, due to the
presence of imaginary roots of its lapse function associated with event
horizon. Moreover, reductions from the Taub-NUT-AdS and Schwarzschild-AdS to
Taub-NUT and Schwarzschild, respectively, are successfully performed. Finally,
we construct the global embedding Minkowski spacetimes for the patches inside
the event horizons of the Taub-NUT-AdS and its extended manifolds.
