Learn Turkish: Anlayış göstermeniz bizim için önemlidir. - Your showing understanding is important for us.

To say 'your showing understanding,' we use the verbal noun gösterme and add the possessive suffix -niz (your). Using the full infinitive göstermek would just mean 'to show understanding' and would not specify who is doing the action.

Is anlayış göstermek a fixed expression?

Yes, it is a very common pairing. While in English we might simply refer to 'your understanding,' Turkish prefers the active phrase 'showing understanding.' You will often see this combination used in formal or polite requests.

Why doesn't anlayış take the accusative suffix here (like anlayışı)?

Because it acts as an indefinite direct object. You are talking about showing understanding in general, not a specific, previously mentioned understanding. When a direct object is non-specific, it stays in its bare form and sits right next to the verb.

What does the -dir suffix in önemlidir add to the sentence?

The -dir suffix makes the statement sound formal, objective, and polite. You will typically see this structure in business emails, public announcements, or official contexts. In a casual conversation, you would drop it and just say bizim için önemli.
