Etymology: The most striking fact about "gunk" is that it was first a brand name. Gunk was a trademarked liquid soap, sold as a strong degreaser for cleaning engines and greasy machinery, and the product's name gave English a word for the sticky grime it was meant to remove. The word itself is probably a blend of "grime" and "funk," the latter a term for a foul smell or dirty muck. Those two sounds fit the sense of something both dirty and unpleasant, though the blend is a plausible guess rather than a documented fact. Whatever its exact parentage, the sense of a greasy, clinging residue came with it. From the trademark, "gunk" spread into general use for any viscous, dirty substance that gums up surfaces, so a product name became an everyday noun for the mess itself.
