Eu vou ligar para você daqui a uma hora.

Ligar has several meanings depending on context:

• ligar para alguém = to call someone (phone)
• ligar (something) = to turn on (a device)
• ligar para (something) can also mean “to care about” (in other contexts)

In your sentence, ligar para você clearly means to call you because of para você (calling to someone).

In Portuguese, the verb ligar meaning “to phone” typically takes para:

• Ligar para você = call you
  Saying ligar você is not standard for “call you” in Brazilian Portuguese.

Both are common, but they reflect different styles/regions:

• Vou ligar para você = neutral and widely acceptable everywhere
• Te ligo (daqui a uma hora) = very common in Brazil, more informal, and uses the object pronoun te (“you” informal) Also common: Vou te ligar.

Both can mean “you (singular),” but usage varies by region and formality:

• você is extremely common across Brazil and takes 3rd-person verb forms (e.g., você vai, você liga).
• tu is common in some regions; it may take 2nd-person forms (tu vais) or, very often in Brazil, tu
  • 3rd-person forms (tu vai), depending on the dialect.

Your sentence uses você, so the rest of the grammar aligns with that.

Daqui a + time means “from now, in (a certain amount of time)”:

• daqui a uma hora = in an hour (from now)

Em uma hora is also possible, but it can feel more like “within an hour / in one hour (duration)” depending on context. If you want the clear “from now” meaning, daqui a is very common and precise.

In standard Brazilian Portuguese, the common structure is daqui a + time expression:

• daqui a uma hora
• daqui a pouco
• daqui a dois dias

In casual speech, some people may drop the a, but daqui a is the safest, most standard form to learn.

In this sentence, daqui a uma hora literally means in one hour.
But uma hora can also mean “sometime” in other contexts, especially in expressions like:

• Uma hora eu te conto. = “I’ll tell you sometime / at some point.”

Here, because it’s tied to daqui a, it’s understood as a specific time: one hour from now.

Yes. Portuguese allows flexible word order for emphasis:

• Eu vou ligar para você daqui a uma hora. (neutral)
• Daqui a uma hora eu vou ligar para você. (emphasizes the time)
• Eu vou ligar daqui a uma hora para você. (possible, but less smooth; most speakers keep para você close to ligar)

More formal/written options include:

• Ligarei para você daqui a uma hora. (simple future, formal)
• Entrarei em contato com você daqui a uma hora. (“I’ll get in touch with you…”, formal)

Your original sentence is perfectly correct—just more conversational.

A rough, English-friendly approximation (varies by region):

• Eu vou ligar para você daqui a uma hora.
  ≈ eh VOH lee-GAR pah-rah vo-SEH dah-KEE ah OO-ma OH-rah

Notes:

• vou often sounds like voh
• final r in ligar is usually a light h sound in many accents
• você is typically stressed on the last syllable: vo-CÊ
