dia duit is basically “God to you,” historically short for “may God be with you / bless you.”

===== - Dia - Noun: ''Dia'' “God” (capitalized when referring to the Christian God). - From Old Irish ''día'', ultimately from Latin ''deus'' (loan via early Christian Latin). =====
'' duit - Prepositional pronoun: ''do'' “to” + ''tú'' “you (sg.)” → ''duit* “to you”. - Same pattern as other prepositional pronouns: - dom “to me” (< do + mé) - duit “to you” - dó “to him” - di “to her”, etc.

So literally:

: 

===== Historically it’s understood as a shortened benediction, something like: =====
'' ''Go mbeannaí Dia duit* “May God bless you.”
* Or more loosely “May God be with you.”

The greeting got reduced to just the core NP + prepositional pronoun: “God to you,” interpreted idiomatically as “hello.”

Plural or polite:
* Dia daoibh “hello (to you pl.)” - daoibh = do + sibh “to you (pl.)”.

===== Modern Standard / Connacht-ish: =====
* Dia duit ≈ /ˈdʲiə d̪ˠɪtʲ/ - Dia → /ˈdʲiə/ (d slender, ia diphthong /iə/) - duit → /d̪ˠɪtʲ/ (broad d, short /ɪ/, slender t).

===== - PIE root ''deiw- / ''dei̯w- “god, sky-being” → =====
'' Latin ''deus* “god” →
'' Early Christian Latin → Old Irish ''día* “god” →
'' Modern Irish ''Dia* “God” →
* Fixed liturgical/benedictory greeting “Dia (go mbeannaí) duit” → modern everyday “hello.”

So dia duit is literally “God (be) to you”, with the verb and mood now implicit.
