We consider the two-dimensional capillary-gravity water waves problem where the free surface Γt intersects the bottom Γb at two contact points. In our previous works \citeMW2, MW3, the local well-posedness for this problem has been proved with the contact angles less than π/16. In this paper, we study the case where the contact angles belong to (0, π/2). It involves much worse singularities generated from corresponding elliptic systems, which have a strong influence on the regularities for the free surface and the velocity field. Combining the theory of singularity decompositions for elliptic problems with the structure of the water waves system, we obtain a priori energy estimates. Based on these estimates, we also prove the local well-posedness of the solutions in a geometric formulation.
