Hello,<br/><br/>Is it ok to hyphen after "marginal"?<br/><br/>For example<br/><br/>the marginal gain investments.<br/>the marginal-gain investments.<br/><br/>It can be investments with marginal gains but I want to know if you need a hyphen if we write it this way.<br/><br/>Second,<br/>Are thrre some words you should not hyphen after? Like those ending in "ly"?<br/>Are words ending in "al" also not hyphenated?<br/><br/>Thank you.
