korkeamääräisillä
Korkeamääräisillä is a Finnish term that literally translates to "in high quantities" or "with high amounts." It is not a standalone noun or adjective with a fixed meaning in the same way that words like "table" or "blue" are. Instead, it functions as an adverbial phrase, describing the manner or extent of an action or state. The core of the word, "korkea," means "high," and "määräinen" relates to "amount" or "quantity." When combined with the illative plural ending "-isillä," it indicates movement into or a state within a condition of high quantity.
This phrase is commonly used in contexts where a large volume or number of something is involved.
