Learn Russian: В этой концепции мы видим иной смысл. - In this concept, we see a different meaning.

While другой is the everyday word for 'other' or 'another' (like an additional object or a different person), иной is often used for things that are fundamentally different in nature, quality, or perspective. With an abstract word like смысл (meaning), иной suggests a completely alternative interpretation or a deeper, qualitatively different meaning.

What case is иной смысл in, and why do the endings look like the nominative case?

It is in the accusative case because it is the direct object of the verb видим (we see). Since смысл is a masculine inanimate noun, its accusative form is identical to its nominative form, and the defining pronoun иной matches this inanimate pattern.

Why does концепции end in -ии? Shouldn't a feminine noun in the prepositional case end in -е?

It is indeed in the prepositional case, answering 'where' and following the preposition в. However, feminine nouns that end in -ия in the nominative (like концепция) follow a special declension rule. Instead of taking the standard -е ending in the prepositional case, they end in -ии.
