Questions & Answers about Kafamda aynı şeyler bir döngü hâlinde dönüp duruyor.

What exactly does Kafamda mean and how is it formed? Is the -da here the same as the particle de/da meaning also?

• Kafamda = kafa (head) + possessive -m (my) → kafam
  • locative -da (in/at/on) → kafamda = in my head.
• The -da here is the locative case suffix, not the clitic de/da meaning also/too.
• Choice of -da/-de/-ta/-te follows consonant voicing and vowel harmony. Because kafam ends with a voiced consonant (m), you use -da (not -ta).

Why is the verb singular (dönüp duruyor) even though the subject (aynı şeyler) is plural?

In Turkish, third-person plural agreement on the verb is optional. With non-human or indefinite plural subjects, the verb usually stays singular. So aynı şeyler … dönüp duruyor is the natural choice. You’d generally use -lar/-ler on the verb mainly for human, specific subjects or when you want to emphasize the plurality: Çocuklar geldi(ler). Here, dönüp duruyorlar would sound odd or unnecessarily heavy.

What nuance does dönüp duruyor add compared to just dönüyor?

• dönüyor = is turning/going around (plain ongoing action).
• dönüp duruyor = keeps turning around, over and over, often with a sense of persistence, monotony, or mild annoyance. Literally it looks like turning and standing, but durmak acts as an aspectual auxiliary here and does not mean to stop.
• Close English feel: keep V‑ing / V‑ing on and on.
