chase, drive away, follow, pursue, meanwhile
追 centers on moving after something: chasing, pursuing, or following. The sense of driving away is a forceful extension of pursuit, and meanwhile can be understood as following along in time.
追 combines the movement radical 辶 with a phonetic component that historically represented a mound or heap, contributing the sound ツイ. The character expresses the idea of moving after something.
The movement radical 辶 suggests motion, and the inner part looks like a simplified mound or target. Picture someone moving along a path chasing after a mound-shaped target.
For ツイ, imagine chasing after two (ツ) things at once, and the chase leads you to say 'Tsu-i!' as you pursue them: two -> ツ, and the whole reading ツイ.
