Polyyppeihin

Polyyppeihin is the illative plural form of the Finnish noun polyypit, meaning polyps. In Finnish, the illative case expresses movement toward or into something, and its plural form is used with plural nouns to indicate direction toward multiple objects. Therefore polyyppeihin translates to into the polyps or toward the polyps in English.

Formation and usage: The base form is polyypit (polyps). The illative plural is polyyppeihin, created by adding the illative plural suffix -eihin to the stem polyyppe-. The form follows general Finnish phonology and vowel harmony rules. Like other illative plurals, it is used with verbs of motion or with phrases that require the illative case to indicate direction toward several polyps.

Usage: The form appears in medical texts, anatomy descriptions, and clinical notes, especially when describing navigation, procedures, or actions directed at polyps. It can be used with verbs of movement, as well as in phrases that specify location or goal related to multiple polyps. It is a standard grammatical form rather than a concept by itself.

Examples:

- Potilas meni polyyppeihin tähystystä varten.

- Endoskooppisen tutkimuksen aikana lääkäri tarkasti polyyppeihin liittyvää kudosvauriota.

Notes: Polyyppeihin is one of several Finnish illative plural forms formed with suffixes such as -eihin, reflecting vowel harmony and the stem consonant structure. It is primarily encountered in technical or clinical Finnish, and is part of normal noun inflection rather than a separate lexical entry.
