For line splits in words ending in -ing, if the final root consonant is doubled before -ing , put the hyphen between the consonants; in other cases hyphenate at the suffix itself:
There are a few "never" rules you should remember when breaking the words at the end of the line:
- Never break up a one-syllable word.
- Never hyphenate a word that already has a hyphen.
- Never split a proper noun (any noun starting with a capital letter).
- Never leave one or two letters on either line. However, you may use hyphen before the inflexion for the past participle (e.g play-ed) with regular verbs, at the same time it is less common for irregular verbs (e.g brok -en).
- Never put the first or last letter of a word at the end or beginning of a line.
- Never start the new line with two-letter suffixes.
