If you look up “hard” in a Finnish dictionary, you will get several translations. This article goes through this options, while especially focusing on kova vs vaikea. Both of these words are adjectives.

This topic was suggested by Joachim on our Discord server. Thanks, Joachim!

1. Difficult vs Solid in Finnish

As a beginner, this first part is the most crucial for you. The adjective “hard” in English can have two meanings. Firstly, a homework can be hard, which means it’s difficult. In Finnish, we generally use vaikea for this purpose. Secondly, a stone or a pillow can be hard, which means it’s solid or firm. In Finnish, this will usually be translated as kova.

In the table below, you can find some example sentences of vaikea vs kova.

2. Ways to say Difficult in Finnish

If you’ve advanced a bit further in your studies, you might benefit from learning some other ways besides vaikea to express that something is difficult. Just like in English you can have several synonyms. English has, for example, strenous, laborious, tough and burdensome. As you can see, these are more advanced adjectives.
