يَا does almost all the work; the others are rare or poetic. The grammarians say every call hides the verb أَدْعُو (“I call”) — which is why the munada after it can take nasab like an object. In the Quran the call is a structural signpost: يَا أَيُّهَا الَّذِينَ آمَنُوا opens a fresh address, and what follows is directed straight at you.

|---|---|---|---|
| 1 | يَا | yā | O — the general call, near or far, and nearly every call in the Quran |
| 2 | أَيَا | ayā | O — for someone far off |
| 3 | هَيَا | hayā | O — for someone far off |
| 4 | أَيْ | ay | O — for someone close by |
| 5 | الْهَمْزَة (أَ) | al-hamza | O — for someone close by |
A munada that is mudaf goes into nasab; one that is a single definite name is mabni on damma. But the nasab is not really the particle's doing: the classical analysis is that يَا stands in for the verb أَدْعُو (I call), and the verb is the 'amil. That is why some grammarians decline to count the vocative particle among the 'awamil at all, even though both Tasheel al-Nahw and Arabic Tutor list it here.
Does the calling particle have to be written?
No. It is often dropped, especially in address to Allah and in elevated speech, and the sentence is still a call. What tells you is the shape of the noun and the sense — the particle is understood even where it is absent.
