・On-yomi (音読み): ⚫︎ト (to) ・Kun-yomi (訓読み): ⚫︎つく (tsuku)

⚫︎ 突然 (とつぜん) Translation: Suddenly; abruptly; unexpectedly. ⚫︎ 突破 (とっぱ) Translation: Breakthrough; penetration; to overcome. ⚫︎ 急に突き出す (きゅうにつきだす) Translation: To suddenly push out; to protrude abruptly.

The kanji 突 is a pictophonetic compound (形声文字, けいせいもじ). The left side is a component suggesting a person or something, and the right side is 犬 (いぬ) which originally looked like "犬" means "dog". The original meaning of the character was related to a dog's behavior, possibly to a dog suddenly jumping or attacking. Over time, the meaning generalized to the action of thrusting or piercing, and the dog-related component was simplified.
