Em/En Dash & Hyphens So, I know what a Hyphen is (or so I thought) but this person is trying to tell me otherwise. I thought Hyphens were made to do the following; -join two or more words serving as a single adjective before a noun, -Use a hyphen with compound numbers, -Use a hyphen to avoid confusion or an awkward combination of letters, -Use a hyphen with the prefixes ex- (meaning former), self-, all-; with the suffix -elect; between a prefix and a capitalized word; and with figures or letters, -Use a hyphen to divide words at the end of a line if necessary, and make the break only between syllables, -For line breaks, divide already hyphenated words only at the hyphen, -For line breaks in words ending in -ing, if a single final consonant in the root word is doubled before the suffix, hyphenate between the consonants; otherwise, hyphenate at the suffix itself. But this person is telling me this; I've taken out pretty much all of my Grammar books, looked at many sites and I've never seen a Hyphen used the way he's thinking it's supposed to mean in this book. Can anyone help out? Thanks for your time.
