How should be the word
parking correctly split at the end of the line? Should it be
ing? The latter is suggested by my word processor, but I would say the former is correct. Which one is it?
The former is how we divide parking into syllables in speech (following the Maximum Onset Principle):
The latter is how we divide parking when we need to break it across lines in writing. We identify the suffix -ing and separate it from the previous morpheme, ignoring pronunciation:
However, there is an exception to this rule. If a letter before the suffix has been doubled, the hyphen goes between the doubled pair:
plan·ning (not *plann·ing)
