  This paper focuses on the strong convergence of the truncated
$\theta$-Milstein method for a class of nonautonomous stochastic differential
delay equations whose drift and diffusion coefficients can grow polynomially.
The convergence rate, which is close to one, is given under the weaker
assumption than the monotone condition. To verify our theoretical findings, we
present a numerical example.
