ivätpäätteellä

ivätpäätteellä is a Finnish suffix used in the third person plural of verbs. It is attached to the verb stem to indicate that the action is being performed by multiple subjects. The suffix -ivät is a past tense marker, so it is used in the past tense conjugation. For example, in the verb "tulla" (to come), the past tense third person plural form is "tulivat" (they came). Here, "tuli-" is the verb stem and "-vat" is the past tense third person plural suffix. The final -t is a plural marker that is often present in the third person plural.

The suffix -ivätpäätteellä can be further broken down. The "-ivät" part signifies the past tense and the third person plural subject. The exact form of the suffix can vary slightly depending on the verb's conjugation class and vowel harmony rules within Finnish grammar. For instance, some verbs might use -ivät while others might use a related form that adheres to the preceding vowels of the verb stem. The addition of "-pä" often adds an emphatic or slightly questioning nuance, though its primary function here is part of the standard inflectional morphology.

In essence, -ivätpäätteellä is a grammatical marker that collectively conveys past tense, a plural subject of the third person, and is integral to forming the correct verb conjugation in spoken and written Finnish when referring to actions done by "them" in the past. Its presence signifies a completed action by multiple individuals or entities.
