Parsing inflected forms may not always work as expected. If the following does not give the correct word, try Latin Words or Perseus.
† hĭĕrātĭcus, a, um, adj., = ἱερατικός, belonging to sacred uses, hieratic: charta hieratica appellatur antiquitus religiosis tantum voluminibus dicata, quae ablutione Augusti nomen accepit, sicut secunda Liviae, a conjuge ejus. Ita descendit hieratica in tertium nomen, Plin. 13, 12, 23, § 74.
