How Vanillin is an example of an aromatic monoterpenes and it has only 8 carbons and not 10 ?

Terpenes are formed in nature by combining isoprenenyl units [ (CH3)C=CHCH2-] as such they are always branched and always contain multiples of five carbon atoms. Vinillin fails on both counts.

From what I can find, vanillin is synthesized in plants from the amino acid phenylalanine, and phenylalanine is not synthesized by a pathway involving monoterpenes. So I don't believe that vanillin should be considered to be a monoterpene. Limonene and menthol are definitely aromatic monoterpenes, but I'm pretty sure that vanillin isn't.
