### note

«Fast» is both adjective and adverb: «a fast car», «she runs fast» (not «fastly»). «Breakfast» is the meal that breaks the night's fast. Maths: «how fast» asks for a speed (distance ÷ time). Trap: faster means less time for the same distance; a clock 5 minutes fast means take away 5 minutes for the real time.
