A compound is the combination of only two words.
Only words of the same parts of speech can be combined to form compounds.
We can always tell by the words a compound contains what it means because the meaning of a compound is always the sum of the meanings of its parts.
The part of speech of the compound is always determined by the part of speech of the second element, without exception.
