Sag (imperative)
‘Sag’ is the du‑imperative of the verb ‘sagen’ (to say/tell). It is used for informal commands.
mir (dative pronoun)
‘mir’ is the dative form of ‘ich’. After verbs of communication like ‘sagen’, the person receiving the information is in the dative.
bitte (politeness particle)
Placing ‘bitte’ after the verb softens the command and makes it polite, similar to ‘please’ in English.
deine (possessive adjective)
‘deine’ agrees with the feminine noun ‘Zimmernummer’ (die Zimmernummer).
Zimmernummer (compound noun)
A compound of ‘Zimmer’ (room) and ‘Nummer’ (number). The whole noun is feminine, so the article is ‘die’.

Cultural Tip
In German‑speaking countries the word order ‘Sag mir bitte …’ is perfectly natural and polite. However, remember that ‘Sag mir …’ is informal. In a hotel reception you would normally say ‘Sagen Sie mir bitte Ihre Zimmernummer.’ Using the formal ‘Sie’ shows respect to guests you do not know personally.
