Common mistakes

  • 熟れる (うれる) is used of fruit ripening; 熟す (じゅくす) is the wider 'mature, become ripe' including plans and conditions.
  • 熟語 is じゅくご — a set compound, not a 'mature word'.

Memory aid

Picture it

Fire 灬 burning underneath: heat applied over time until food is cooked through and fruit is ripe, so the kanji means 'mature'.
