bangohan no ato, kazoku to issyo ni terebi wo mimasu.

Japanese often leaves out the subject when it is clear from context. So instead of saying I watch TV with my family after dinner, Japanese can simply say After dinner, with family together, watch TV and let the listener infer the subject.

Depending on context, this could mean:

• I watch TV...
• We watch TV...
• sometimes even they watch TV...

In beginner materials, it is often understood as I unless the context says otherwise.

晩ご飯 means dinner and あと means after.

The particle の connects the noun 晩ご飯 to あと, so 晩ご飯のあと literally means the after of dinner, which is the natural Japanese way to say after dinner.

This pattern is very common:

• 学校のあと = after school
• 仕事のあと = after work
• 映画のあと = after the movie

So の is linking one noun to another.

The comma separates the time phrase from the rest of the sentence.

So the structure is:

• 晩ご飯のあと、 = after dinner,
• 家族と一緒にテレビを見ます。 = watch TV together with family.

The comma is not always required, but it is very common and helps readability, especially when a sentence starts with a time expression.

Yes, in most contexts 家族 here is understood as my family or the family relevant to the speaker.

Japanese often does not use words like my when the meaning is obvious. So:

• 家族 can mean family
• in context, it often naturally becomes my family

This is another example of Japanese leaving out information that English usually states explicitly.

Because they do different jobs:

• と means with
• 一緒に means together

So 家族と一緒に means together with family.

You can think of it as emphasizing companionship a little more than just 家族と.

Compare:

• 家族とテレビを見ます。 = I watch TV with my family.
• 家族と一緒にテレビを見ます。 = I watch TV together with my family.

Both are natural, but 一緒に adds the idea of doing it together.

Yes, absolutely.

家族とテレビを見ます is grammatically correct and natural. It simply means I watch TV with my family.

Adding 一緒に makes the sense of shared action clearer or a little more explicit:

• 家族とテレビを見ます = with my family
• 家族と一緒にテレビを見ます = together with my family

So 一緒に is not required, but it is very common.

In this sentence, 一緒に functions adverbially, meaning together.

The に helps turn 一緒 into something that modifies the verb 見ます. In other words, it tells you how the action is done:

• 一緒に見ます = watch together

This is common with many words of this type:

• 静かに話します = speak quietly
• きれいに書きます = write neatly

So here, 一緒に modifies 見ます.

The particle を marks the direct object of the verb.

Here, the verb is 見ます (to watch / to see), and the thing being watched is テレビ.

So:

• テレビを見ます = watch TV

This is a very standard pattern:

• 本を読みます = read a book
• 映画を見ます = watch a movie
• 音楽を聞きます = listen to music

Because in Japanese, you see/watch TV, not do TV.

English says watch TV, and Japanese uses the verb 見る for that:

• テレビを見る = watch TV

By contrast, する is used with things you do, such as:

• 勉強する = study
• 仕事する = do work / work
• 運動する = exercise

So テレビを見ます is the normal expression.

Japanese is basically a subject-object-verb language, so the verb usually comes at the end of the sentence.

This sentence is structured like:

• 晩ご飯のあと = after dinner
• 家族と一緒に = together with family
• テレビを = TV
• 見ます = watch

So the final verb is completely normal for Japanese.

The plain-form version is:

晩ご飯のあと、家族と一緒にテレビを見る。

Here:

• 見ます is the polite form
• 見る is the plain form

The meaning stays the same. The difference is politeness and style.

No. Common alternatives include:

• 晩ご飯（ばんごはん）
• 夕飯（ゆうはん）
• 夕食（ゆうしょく）

Very roughly:

• 晩ご飯 and 夕飯 feel everyday and casual
• 夕食 can sound a little more formal or neutral

All can mean dinner, though nuance depends on context.

You are right: normal Japanese writing usually does not use spaces.

This sentence would normally be written as:

晩ご飯のあと、家族と一緒にテレビを見ます。

Spaces are often added in teaching materials for beginners to make the parts easier to see. They are not standard in ordinary Japanese writing.

They are very close.

• 晩ご飯のあと = after dinner
• 晩ご飯の後で = after dinner / after having dinner

Both are natural. あと by itself is very common, and 後で can sometimes feel a little more like after that or after doing that, depending on context.

For a beginner, it is safe to understand them as very similar here.

Yes, if the meaning changes accordingly.

For example:

• みんなと一緒にテレビを見ます。 = I watch TV together with everyone.
• 彼らと一緒にテレビを見ます。 = I watch TV together with them.

But in natural Japanese, people often prefer specific nouns like 家族, 友だち, or 弟 rather than pronouns, especially when the relationship is clear.

A very literal breakdown is:

• 晩ご飯 = dinner
• の = linking particle
• あと = after
• 家族 = family
• と = with
• 一緒に = together
• テレビ = TV
• を = object marker
• 見ます = watch

So the sentence is roughly:

After dinner, together with family, TV watch.

That sounds unnatural in English, but it matches Japanese structure more closely.
