Learn Hardcore Chinese: wǒ yǐjīng huí jiā le.

The sentence‑final 了 (le) marks a change of state or a new situation. In 我已经回家了, it signals that the situation “I am home / I’ve gone home” is now true. This is different from the verb‑suffix 了 (the perfective), which goes right after the verb to mark completion of the action itself (see below).

Do I need both 已经 and 了? Aren’t they redundant?

They’re not redundant; they do different jobs:

已经 is an adverb meaning “already,” emphasizing timing.
Sentence‑final 了 signals a new situation/result now holds.

Comparisons:

我回家了 = I’ve gone home / I’m home now.
我已经回家了 = Same meaning, but with extra emphasis on “already.”
我已经回家 is usually incomplete in standard speech; add 了 or a past time word: 我昨天已经回家了.

Can 了 go after the verb instead (e.g., 我回了家)?

Yes, but it changes the feel. 我回了家 uses the perfective 了 after the verb, focusing on the completion of “returning home” as an event. As a standalone sentence it can sound abrupt; it’s more natural with a time or follow‑up:

我昨天回了家。
我回了家，就睡觉了。 By contrast, 我回家了 (sentence‑final 了) highlights the new state (“I’m home now” / “I’ve gone home”).

How do I say “I haven’t gone home yet” or “I didn’t go home”?

Use 没(有), not 不, to negate past/completed actions.

Not yet: 我还没(有)回家（呢）。
Didn’t (at that time): 我没(有)回家。
Don’t/won’t (habit/decision): 我不回家。 (different meaning)

What’s the difference between 回家, 到家, and 回到家?

回家: “go/return home” (neutral about the exact moment of arrival; context decides).
到家: “arrive home.” 我到家了 unambiguously means “I’ve arrived.”
回到家: combines “return” + “arrive”; it emphasizes reaching home: 我已经回到家了。

How do 回来, 回去 compare with 回家了?

They add direction relative to the speaker/listener:

我回来了！ = I’m back (to where you are).
我回家了。 = I’m going home/I’ve gone home (away from where you are).
他回去了。 = He went back (away from here).

Where does 已经 go? What about time words?

Typical order: Subject + (time) + 已经 + Verb Phrase + (other info) + (sentence‑final 了).

我昨天已经回家了。 Avoid placing 已经 after the verb or at the very end:
✗ 我已经昨天回家了。 (unnatural)
✗ 我回家已经了。 (wrong)

How do I ask “Have you (already) gone home?” or “Are you home yet?”

你回家了吗？ (Have you gone home?/Are you home yet?)
你已经回家了吗？ (emphasizes “already”)
你到家了吗？ (Have you arrived home?)
你回家了没有？ (colloquial yes/no check)

How do I say “I just got home”?

Use 刚/刚才:

我刚到家(了)。
我刚回到家(了)。 With 刚/刚才, sentence‑final 了 is optional; both forms are common.

How do I express duration, like “I’ve been home for two hours”?

Use a duration + 了 pattern:

我已经在家两个小时了。
我到家已经两个小时了。 These mean the state has lasted up to now.

Why no preposition like “to,” or a measure word before 家? Can I say 回家里?

With motion verbs like 回, you put the destination directly: 回 + place. 家 is a place word here, so no preposition/measure word. Don’t say 回家里. For possession:

Natural: 回我家
Emphatic/contrasting: 回我的家 (heavier, used when stressing “my”)

How is 了 pronounced here? Is it le or liǎo?

Here it’s the neutral‑tone particle le. The liǎo reading appears in other words (e.g., 了解), not as the sentence‑final change‑of‑state particle.

Can 我回家了 mean “I’m about to head home now”?

Yes, when said right before leaving, 我回家了 often means “I’m heading home now” (announcing an imminent change). If you want to be extra clear about “about to,” say 我要回家了. With 已经 (我已经回家了), it means the action is done—“I’ve already gone home.”
