Make It Stick

  • Think of "lassitude" like "tired" (A1 word), but much stronger and longer-lasting—like you want to rest and cannot do much
  • Picture a person after a long day in the sun, feeling very weak and slow, like their body is heavy and slow
  • It's the feeling you get when you want to sit down and do nothing because you have no energy left
  • Sounds like "LA-sih-tude" → imagine someone saying "last attitude" but they have no energy left for any attitude
  • Imagine a slow, quiet afternoon where everything feels calm but also very still because of tiredness
  • NOT like "sleepy" (just needing sleep), lassitude is more about weak energy and lack of strength, not just wanting to sleep

  • NOT like "lazy" (choosing not to do work), lassitude is a feeling you cannot control, not a choice
