süstis

Säästis is a Finnish colloquial noun used to refer to saving or savings, especially in informal speech. The term can denote a personal saving habit, a physical piggy bank, or a savings account, depending on context. It is not a formal financial term and does not appear in standard dictionaries with a fixed definition; its meaning shifts with usage.

In everyday use, people may say they are putting money into their säästis or that their säästis is growing, meaning their savings. In marketing or media, säästis is occasionally used as a brand name or campaign theme to highlight budgeting, frugality, or financial education. The word can also appear in youth language to personify savings as an object or concept that one protects.

Origin and related terms: Säästis is formed from säästö, the standard word for saving, with informal suffixes allowing playful or affectionate meaning. It shares the core idea of saving with related terms such as säästö (saving) and säästötili (savings account).
