adumbration

From Latin adumbrātiō (“sketch; outline, silhouette; pretence, semblance”) + -ion (suffix indicating a condition or state). Adumbrātiō is derived from adumbrāre (present active infinitive of adumbrō (“to represent an object with light and shade, to shade; to represent in outline, to outline, silhouette, sketch; to cast a shadow on, overshadow, shade; to copy, counterfeit, imitate”)) + -tiō (suffix forming nouns relating to actions or the results of actions). Adumbrō is derived from ad- (prefix meaning ‘to, towards’) + umbrō (“to cast a shadow, to shade; to overshadow”) (from umbra (“shade; shadow; ghost”)).
