Hyphenation compound words

As you learned in the rule about the use of hyphens, there are specific instances where hyphens are used in combining words. Hyphens are used when forming adjectives that appear before a noun, for example. In creating compound words, hyphens are not used. In most cases, you will merge the two words with their spelling intact.

An exception to this mle—use Christlike. Do precede like with a hyphen if the word is a compound word. On the other hand, when like is a prefix, then follow with a hyphen when used as a prefix meaning similar to, e.g., like-minded.

Use of hyphens single- and multiple-word names. The general rule is to determine whether the parent is itself an element or compound. If so, then the name is written as a single word if not, then the name is written as multiple words. Methylbenzene is written as one word, for instance, because the parent—benzene—is itself a compound. Diethyl ether, however, is written as two words because the parent—ether—is a class name rather than a compound name. Some further examples follow ... 

Two- and three-word modihers can be used with compound nouns (i.e., two or more terms used to express a single idea).

In the language of chemical nomenclature, the simple names of atoms are the words. As words are assembled to form a sentence, so names of atoms are assembled to form names of chemical compounds. Syntax is the set of grammatical rules for building sentences out of words. In nomenclature, syntax includes the use of symbols, such as dots, commas and hyphens, the use of numbers for appropriate reasons in given places, and the order of citation of various words, syllables and symbols. 

The compound on the left is numbered correctly since the methyl group is located at carbon 2 of the pentane chain in the compound on the right, the methyl group is located at carbon 4.

So far our discussion has centred on whether forms which we normally delimit by whitespace should be considered as full words or further broken down, and we have seen that apart from a few exceptions, whitespace in conventional writing is actually a quite reliable guide as to word boundaries. But there are certain cases where we can argue that forms separated by whitespace should in fact be treated as a single word. Most of this involves issues to do with hyphens and compounding. Consider the following examples ...
