Practicality → It is formed from "practical" (from Latin *practicus*, meaning effective or active) and "-ity" (a suffix used to form nouns indicating a state or condition). The word "practicality" refers to the state of being practical or the quality of being effective in real situations.
Think of being 'effective' ('practicus') in real-life situations, and the '-ity' shows it's a state or quality. This helps you remember that practicality means the quality of being practical.
