Questions & Answers about Мы обсудили интерьер с дизайнером.

What does the verb обсудили indicate in terms of aspect and tense?

Обсудили is the past tense, plural form of the perfective verb обсудить (to discuss). Its perfective aspect shows that the action was completed, and it agrees with мы (we) as its subject.

Why is there no article before интерьер, even though in English we say the interior?

Russian does not use articles at all. Nouns such as интерьер stand alone without a definite or indefinite article, with context and word order providing any necessary indications of specificity.

Why is дизайнером used instead of дизайнер in the phrase с дизайнером?

The preposition с (with) in Russian requires the following noun to be in the instrumental case. Дизайнером is the instrumental singular form of дизайнер, indicating the means or company involved in the action.

What case is интерьер in, and why doesn't its form appear different?

Интерьер functions as the direct object of обсудили, which would typically be in the accusative case. However, because интерьер is an inanimate masculine noun, its accusative form is identical to its nominative form, so no visible change occurs.
