The suffix ～力 (りょく) attaches to nouns or verbs to indicate the "power" or "ability" related to that word. It is commonly used to describe various skills, capacities, or strengths, such as 計算力 (calculation ability), 集中力 (concentration), or 表現力 (expressive power).

Tips for Learners
Be careful not to confuse ～力 with just "power" in a physical sense; it often refers to abstract abilities or skills. Also, ～力 is a noun suffix, so it usually follows a noun or verb stem and forms a compound noun. For example, 勉強 (study) + 力 = 勉強力 (study ability), though some combinations are more natural than others.
Understanding this suffix will help you recognize and form many useful compound nouns describing abilities in Japanese.
