Dar is to give, and I give is doy, ending -oy like boy. You have met that ending before in voy.
Lo doy · Los doy · Las doy · Él da · Ella da · Ellos dan · Tú das
Where English says they give it to me, Spanish says they give me it. The personal word comes first, and the position rule is the one you already know.
me lo dan (they give it to me)
Él me da algo · Me dan algo · Ellos me lo dan · Te lo doy mañana · ¿Me lo da mañana? · ¿Nos lo dan mañana?
Te lo doy mañana is a very common, very Spanish-sounding sentence. I give you it tomorrow sounds strange in English but is perfect Spanish, using future context instead of a future tense.
Sentences that look complicated in English are not complicated in Spanish. Are you giving it to me tomorrow? has a lot going on grammatically in English and almost none in Spanish.
For I want to give it to you: settle quiero dar first, then the te and the lo, then the order → te lo quiero dar.
Note the trap: to give you is not you give. The student reaches for "das" and has to come back to dar.
If a word ends in a consonant, you do not just add -s, you add -es.
usted → ustedes
¿Ustedes nos lo dan mañana?
Usted, yo, él and ella can move around the sentence for different emphasis. All three of these are fine:
¿Usted me lo da mañana? · ¿Me lo da usted mañana? · ¿Me lo da mañana usted?
When the student answers with a guess, the teacher can tell from the look on their face. The instruction is to establish your own thought process for finding the answer, rather than producing something and checking whether it lands.
Ellas me lo dan works exactly as ellos me lo dan, for a female they.
