hyphenations: many phrases are clarified when augmented by a hyphen; the following architectural terminology is clarified by employing the general rules of hyphenation:

  1. in general, hyphenate an adjectival construction, one that which precedes the subject
  2. in general, do not hyphenate an “ly” word, including “federally”
  3. do not hyphenate “late” or “early” before a century
