Where does “consonantal” come from?

I appreciate the detailed instructions, but I need to flag a problem: the etymology chain provided (consonant → aldehyde → German Aldehyd) doesn't connect to the headword "consonantal."

I cannot write an accurate etymology sentence using this chain, as doing so would violate the core rule: "State only what the chain supports." Using this chain for consonantal would invent a false connection. Could you verify the correct chain for consonantal, or confirm this is a test of the rules?
