KPT Consonant Gradation
In Finnish, words often change their spelling slightly when you add endings to them. This is called consonant gradation, and it mostly affects the letters K, P, and T.
Think of it like the words are putting on different outfits for different occasions! The "strong" form is for everyday use, and the "weak" form is for when we add endings.
