Each week of 2017 we present an English idiom.
“to scratch the surface”: to deal with something only in a superficial way that doesn’t deal with the main issue; nur an der Oberfläche kratzen
Example 1: The team-building weekend was helpful, but it only scratched the surface when it comes to solving the issues among the employees.
Example 2: It’s a start, but the amount of money promised by the government will only scratch the surface. It isn’t enough to deal with the root of the problem.
