As far as I know (-dIğI kadarıyla)

Expressing Limited Knowledge

When you want to state a fact but acknowledge that your perspective or information might be incomplete, you use phrases like "as far as I know" or "from what I see." In Turkish, this is done using the structure -dIğI kadarıyla.

This construction is built in four steps:

1. The verb root (e.g., bil- for "to know")
2. The participle suffix -dIk (which softens to -dığ, -diğ, -duğ, or -düğ because of the following vowel)
3. A possessive suffix showing whose perspective it is (e.g., -im for "my")
4. The fixed word kadarıyla (which literally means "with its amount/extent")

• bilmek (to know) -> bildiğim kadarıyla (as far as I know)
• duymak (to hear) -> duyduğum kadarıyla (as far as I have heard)
• anlamak (to understand) -> anladığım kadarıyla (as far as I understand)
• görmek (to see) -> gördüğüm kadarıyla (as far as I see)

Changing the Subject

Because the subject is indicated by the possessive suffix attached to the verb, you can easily change "as far as I know" to "as far as we know" by simply swapping the "my" suffix (-im) for the "our" suffix (-imiz).

• bil-
  • diğ
    • imiz
      • kadarıyla = bildiğimiz kadarıyla (as far as we know)

Gathering Local Knowledge

This structure isn't limited to basic verbs of perception. You can attach it to any verb related to memory, observation, or information gathering. As you ask around town or look into local rumors, you can apply the exact same formula to verbs like soruşturmak (to investigate), hatırlamak (to remember), or gözlemlemek (to observe).
