Based on the ideas of \it quantum extension and \it quantum conditioning, we propose a generic approach to construct a new kind of entanglement measures called \it conditional entanglement. The new measures, built from the known entanglement measures, are convex, automatically \it super-additive, and even smaller than the regularized versions of the generating measures. More importantly, new measures can also be built directly from measures of correlations, enabling us to introduce an \it additive measure and generalize it to a multipartite entanglement measure.
