The rubric is perhaps not totally clear. The plaintext answers to the clues in *italics* (which are nevertheless 'normal' clues in the sense of being definition and wordplay in either order), together with the corresponding checked letters in their ciphertext entries in the diagram, are enough information to deduce the codeword. If you want to do this manually, note that if the same letter appears in a plaintext digraph and in its enciphered digraph, then both letters of the plaintext appear in either the same row or the same column of the Playfair square. Alternatively (and more easily), enter the plaintext and ciphertext digraphs which you have into a web-based Playfair codeword finder.
