Put the hyphen at the end of the line, not the beginning of the next line:

Make sure each component of the word has at least 3 letters (unless the hyphen occurs after a 2-letter prefix or in a compound word whose first part has only 2 letters – see below):

You can divide the word:

• between syllables

• between prefixes and base words (see Prefixes for a list of common prefixes)

• between the 2 halves of a compound word (see Compound words for more examples of such words)
