Which word implies a sense of elusiveness or inaccessibility in its ornamental context?

The word that implies a sense of elusiveness or inaccessibility in its ornamental context is "filigree." This term specifically refers to delicate and intricate ornamental work made with fine wires, often in gold or silver. The art of filigree involves weaving or twisting these fine metal threads into ornamental designs, which can create a sense of ethereality and complexity. Its elaborate and detailed nature lends itself to an impression of being elusive or difficult to grasp fully, especially in its beauty or craftsmanship.

In contrast, the other words listed do not carry the same connotation of ornamentation or elusiveness. "Fetid" describes something that is offensive-smelling and has no connection to ornamental contexts. "Felicitous" means well-suited or apt, which does not imply any sense of elusiveness. "Froward" refers to someone who is difficult to deal with or contrary, lacking any association with intricacy or ornamental qualities. Thus, "filigree" is the clear choice when discussing elusiveness in an ornamental context.
