Questions & Answers about Подпись клиента необходима для заключения соглашения.

Why is подпись клиента in the nominative case?

Because it functions as the grammatical subject of the sentence. In Russian, the subject is in the nominative, and the short-form adjective необходима agrees with it (feminine singular).

Why is клиента in the genitive case?

This is the possessive or “of” relationship: подпись кого? — клиента. In Russian, the noun that denotes “whose signature” takes the genitive.

Why is необходима in the short feminine form?

Short-form adjectives used predicatively agree in gender, number, and case with their subject. Here подпись is feminine singular, so the adjective is необходима (short, feminine, singular).

What part of speech is заключения, and why is it used here?

заключения is a deverbal noun (отглагольное существительное) formed from the verb заключить with the suffix -ение. It lets you turn the action “to conclude” into a noun that can follow the preposition для.

Why isn’t the infinitive заключить used after для?

The preposition для requires a noun in the genitive, not an infinitive. So you nominalize the verb (“заключить” → “заключение”) to fit the grammar.
