Likaisuus

Likaisuus is a Finnish noun that denotes the state or quality of being dirty or filthy. The term can describe physical dirt on surfaces, objects, or people, as in contexts dealing with cleanliness, hygiene, or sanitation. It also has a figurative use to refer to moral or ethical impurity, wrongdoing, or corruption, for example in discussions about reputational risk or scandal. The word derives from likainen meaning dirty and the abstract noun suffix -isuus, with the root lik a meaning dirt, grime, or mud.

In everyday language, likaisuus is used to describe how dirty something is, often with attention to visible grime. In hygiene and maintenance contexts, people may speak of the “likaisuus” of a surface or use related terms like lika or saastuminen; depending on nuance, other words may be chosen for precision. Metaphorically, likaisuus can describe unethical practices or a corrupt environment, though this usage is typically informal or expressive rather than technical.

The term is part of standard Finnish vocabulary and is understood by speakers across regions. It is commonly used in descriptive statements: “Pöydän likaisuus vaatii puhdistamista” (The table’s dirtiness requires cleaning). In more formal or technical writing, other terms such as saaste, lika, or puhtausmight be preferred for precision, but likaisuus remains a valid descriptor in ordinary language.
