(location) there (away from the speaker, but close to the listener)
Coordinate terms: duman, digdi

diyan

dian — now dialectal
d'yan — contraction
diyaan, dyan, dyaan — nonstandard
jan — Internet slang, text messaging
riyan — dialectal, Rizal, after words ending with vowels, ⟨w⟩, or ⟨y⟩ (in standard Tagalog)

The latter half of the word is possibly iyan. See also dito, doon, niyan, nito, niyon/noon, and other Tagalog demonstrative pronouns. Compare Bikol Central diyan, Pangasinan ditan, and Western Bukidnon Manobo diyan. Meanwhile, the former half is possibly related to Malay di and Indonesian di as a likely cognate.

diyán (Baybayin spelling ᜇᜒᜌᜈ᜔)

When the preceding word ends with a vowel, ⟨w⟩, or ⟨y⟩, riyan is used instead, but is not often used in conversation. Other words with this phenomenon include dito, doon, daw, and din.
