Where does “bardic” come from?

I need to work through this chain carefully, but I notice there are problems with the data provided. The chain shows: English bard | French -ique | Latin -icus | Proto-Indo-European -kos | Latin -are | Proto-Indo-European -kos | Latin -are | French -er This chain has repetitions (Proto-Indo-European -kos appears twice, Latin -are appears twice) and doesn't form a coherent path from "bardic" backwards through etymological stages. Additionally, the suffix chain doesn't logically connect to explain "bardic" as an adjective form. The headword is "bardic" (meaning unknown is stated), but I cannot reliably trace how these elements combine to form this word, nor can I determine what sense development occurred. Following your rules strictly—"State only what the chain supports. Do not invent dates, cognates, or intermediate steps"—
