katkeroida

Katkeroida is a Finnish verb that translates to "to embitter" or "to make bitter" in English. It is derived from the Finnish adjective "katkera," meaning bitter. The verb can be used in both literal and figurative senses.

Literally, katkeroida can describe the act of adding something bitter to food or drink, thus making it taste bitter. For example, one might katkeroida a soup by accidentally adding too much of a bitter herb.

More commonly, katkeroida is used figuratively to describe the process of making someone feel resentful, disillusioned, or unhappy due to negative experiences. A person's hopes can be katkeroida by repeated failures, or a relationship can become katkeroida by betrayal. The feeling of being katkeroida implies a lasting sense of bitterness and a loss of previous positive emotions or outlook. The past experiences that lead to this state are often perceived as unfair or deeply disappointing. The outcome is a person or situation imbued with a sense of negativity and a diminished capacity for joy or trust.
