A phrasal compound is a group of words that express a complex meaning, but are not formed through the usual noun or verb modification. They may be idiomatic phrases, such as middle of the road.. Or they may, because of the varied uses of the words, have more than one meaning. Examples of phrasal adjectives:
A compound is a substance in which atoms of different elements are chemically held to one another. A mixture is a substance made by combining two or more different materials in such a way that no chemical reaction occurs.A mixture can usually be separated back into its original components, a compound can not.  The difference is that a compound is a chemically combined  'mixture' (well defined, with one set of properties) and a mixture  is not chemically combined (in a non-defined, variable combination  of compounds and/or elements, all with its own properties:  kerosine/gasoline/naphta, moist/dry air).
