Gefriert

Gefriert is a form that is sometimes encountered in German texts, but it is not a standard finite form of the verb frieren. The verb frieren means “to freeze.” In regular present-tense conjugation the forms are: ich friere, du frierst, er friert, wir frieren, ihr friert, sie frieren. The correct past participle of frieren is gefroren, and the compound forms use ge- with other verbs (for example gefroren as the adjectival past participle).

Because frieren forms a regular past participle as gefroren, the sequence ge- plus a present-tense form such as friert does not correspond to a standard grammatical form. Consequently, gefriert is commonly a misspelling or a mistaken attempt to form a participle or a tense. In practice, native speakers would write es friert (it is freezing) for present-tense meaning, or es ist gefroren / der See ist gefroren for the past or resulting state of being frozen.

Usage notes and examples: Es friert heute stark outside means it is very cold outside. Der See friert zu means the lake is starting to freeze over, while Der See ist gefroren describes that the lake is already frozen. The related noun gefrieren or the process gefriert tipping into freeze-drying or cryogenic contexts appear in technical language.

In short, gefriert is not a standard form in modern German; the correct expressions rely on frieren in its present tense or gefroren as the past participle.
