Here, と means with.

So 家族と暮らしました means lived with family. In this sentence, と marks the person or group you lived together with.

Examples:

• 友だちと暮らしました。 = I lived with a friend / friends.
• 一人で暮らしました。 = I lived alone.

Japanese often leaves that kind of information unstated when it is obvious from context.

So 家族 can often be understood as my family in a sentence like this, even though there is no separate word for my.

If needed, Japanese can be more explicit:

• 私の家族と暮らしました。 = I lived with my family.

But in many situations, just 家族と sounds perfectly natural.

Japanese very often omits the subject when it is already clear from context.

So 家族と暮らしました。 could mean:

• I lived with my family
• He lived with his family
• She lived with her family

The exact subject depends on the surrounding conversation or text.

This is one of the most common differences from English: Japanese does not need to state the subject every time.

暮らしました is the polite past affirmative form of the verb 暮らす.

Breakdown:

• dictionary form: 暮らす
• polite non-past: 暮らします
• polite past: 暮らしました

So this sentence is in the polite style and refers to the past.

暮らす means to live, but it often has a nuance of living one’s daily life or spending one’s life in a certain way.

住む also means to live / reside, but it focuses more on where someone resides.

Very roughly:

• 住む = reside, live in a place
• 暮らす = live, carry on daily life

Examples:

• 東京に住んでいます。 = I live in Tokyo.
• 家族と暮らしています。 = I live with my family.

In many everyday situations, they can overlap, but 暮らす often feels a bit more about lifestyle or living together.

家族 usually means family as a group.

So in this sentence, it normally means one’s family / household / family members together, not just one specific relative.

If you want to talk about one family member, you would usually use a more specific word, such as:

• 母 = mother
• 父 = father
• 兄 = older brother
• 姉 = older sister

Yes, depending on context, English may translate it as either:

• lived with family
• used to live with family

Japanese past tense does not always match English tense choices one-to-one. The sentence simply says that this was true in the past.

If you want to emphasize an ongoing past situation more clearly, Japanese often uses ～ていました:

• 家族と暮らしていました。

That often sounds more like was living with family or used to live with family, depending on context.

Yes, it is a complete sentence.

Even though it is short, it has:

• a noun phrase: 家族と = with family
• a verb: 暮らしました = lived

Japanese sentences can be very short if the omitted information is understood from context.

Those spaces are usually just for learners.

Normal Japanese writing would usually be:

• 家族と暮らしました。

Japanese does not normally use spaces between words the way English does.

It is natural, especially if the context is already clear.

But in real conversation, people might also say:

• 家族と一緒に暮らしました。 = I lived together with my family.
• ずっと家族と暮らしました。 = I lived with my family all along.
• 家族と暮らしていました。 = I was living / used to live with my family.

So 家族と暮らしました。 is fine, but in actual use, speakers often add extra words if they want to make the meaning more specific.
