We establish the embedding of the critical Sobolev-Lorentz-Zygmund space $H^{n/p}_{p,q,λ₁,...,λₘ}(ℝⁿ)$ into the generalized Morrey space $ℳ_{Φ,r}(ℝⁿ)$ with an optimal Young function Φ. As an application, we obtain the almost Lipschitz continuity for functions in $H^{n/p + 1}_{p,q,λ₁,...,λₘ}(ℝⁿ)$. O'Neil's inequality and its reverse play an essential role in the proofs of the main theorems.
