• Write one sentence a day — Not twenty. Just one new word in a real sentence forces understanding.
• Link words to real people — “My teacher is the most kindhearted person I know.” Real connections stick.
• Flashcards with examples — A card that shows a word in a real sentence beats a definition alone every time.
• Say them out loud — Kaleidoscopic, knightly, kismet — K words have satisfying sounds that help them stick.
