Model Answer

The 'p' in pH stands for 'potenz', a German word meaning power.

Source: Chapter 2, Section 2.3 — How Strong Are Acid or Base Solutions?

Explanation

The examiner expects both pieces of information: the word 'potenz' and its language (German) and meaning (power). Missing either part may cost the mark. Keep it to one line.
