These will not be gismu, but either lujvo (you have acid, alkali, salt, sugar, fat, carbon, hydrogen, oxygen and alcohol to work with) or fu'ivla.

Use a name (la 2,3-dimethyl octa-5-enyl 2,4,6-methyl benzoate), or use Mex. lojbab -- lojbab lojbab@lojban.org Bob LeChevalier, President, The Logical Language Group, Inc. 2904 Beau Lane, Fairfax VA 22031-1303 USA 703-385-0273 Artificial language Loglan/Lojban: http://www.lojban.org
