punctual

The Latin word pungere, meaning “to prick” or “to pierce,” and its form punctus give us the roots pung and punct. Words from the Latin pungere have something to do with pricking or piercing. To puncture is to pierce with something pointed. A pungent smell is one that is so strong and sharp that it pierces the nose. Someone punctual acts at the exact point when the hands of the clock prick the right moment. Punctuation pierces a string of words to form separate sentences.
