Other forms: animated; animating; animates; animatingly
At its most basic, animate means simply alive, while inanimate means not living, not moving around. But animate also means spirited, or brought to life.
Animated cartoons are what we think of as pictures come to life: animation. Animate derives from the Latin anima "life, soul, spirit." When you seem particularly filled with life, or high-spirited, if you laugh loudly, or use broad gestures, you're animated.
