In this paper, we construct degenerate soliton solutions (which preserve \(\mathscr {PT}\)-symmetry/break \(\mathscr {PT}\)-symmetry) to the nonlocal Manakov system through a nonstandard bilinear procedure. Here, by degenerate we mean the solitons that are present in both the modes which propagate with same velocity. The degenerate nonlocal soliton solution is constructed after briefly indicating the form of nondegenerate one-soliton solution. To derive these soliton solutions, we simultaneously solve the nonlocal Manakov equation and a pair of coupled equations that arise from the zero curvature condition. The latter consideration yields general soliton solution which agrees with the solutions that are already reported in the literature under certain specific parametric choice. We also discuss the salient features associated with the obtained degenerate soliton solutions.
