Several interrogatives appear close in ordinary translation but differ in their primary targets:
kayfa (كيف) — state or manner: “How are you?”
ayna (أين) — place: “Where is Zayd?”
matā (متى) — time: “When will he come?”
ayyāna (أيان) — future time, often in solemn contexts.
annā (أنّى) — “whence” or “how,” depending on context.
«أَيَّانَ يَوْمُ الدِّينِ»
When is the Day of Recompense?
«أَنَّى لَكِ هَذَا»
Where did this come to you from?
A single English gloss can conceal a rhetorical difference. With annā in particular, the context and the question's actual object must control the interpretation.
