Translation guide
Expressing 'before and after' in Japanese involves different structures depending on whether you're talking about time, order, or physical position. The most common patterns use 前 (mae) for 'before' and 後 (ato) for 'after', but word order and particles differ from English.
Describing what happens before and after a specific event or action.
Use this pattern to say 'before and after N', where N is a noun representing an event or time. 前 means 'before' and 後 means 'after'. The particle と connects them.
食事の前と後に手を洗います。
I wash my hands before and after meals.
Please check the materials before and after the meeting.
For verbs, use the dictionary form before 前 and the past (ta-form) before 後. This pattern is used when the same action is done before and after something.
寝る前と起きた後にストレッチをします。
I stretch before going to bed and after waking up.
Adding で after 後 is common when the after-clause sets the context for an action. It's often interchangeable with just 後.
走る前と走った後で、水分をとりましょう。
Let's hydrate before and after running.
Referring to the period before and after a point in time, without a specific event.
前後 (zengo) means 'around that time' or 'before and after'. It's used to refer to a vague time period surrounding a mentioned point.
彼は昼頃に来ると言っていたが、その前後には電話がつながらなかった。
He said he'd come around noon, but I couldn't reach him around that time.
Means 'around the same time' or 'one after another'. Used when events happen in close succession.
二人は前後して到着した。
The two arrived one after the other.
Describing physical position in front of and behind something.
For physical location, use 前 (mae) for 'front' and 後ろ (ushiro) for 'back/behind'. Note that 後 (ato) is not used for spatial 'behind'.
家の前と後ろに庭があります。
There are gardens in front of and behind the house.
Indicating the order of items or events.
Can mean 'order' or 'context'. Often used in phrases like 前後関係 (context/order of events).

Please explain the context (what happened before and after).
Means 'reversed order' or 'backwards'.

Showing a change or contrast between two states.
Loanword from English, commonly used in makeover or renovation contexts. Often written in katakana.

Can be used for comparisons, but ビフォーアフター is more natural for makeover-style contrasts.
ダイエットの前と後の写真を比べた。
I compared photos from before and after the diet.
後 (ato) is for time/order ('after'), while 後ろ (ushiro) is for physical position ('behind'). Using 後 for spatial 'behind' is incorrect.

Standing behind the car.
前後 is a compound word meaning 'around that time' or 'order', while 前と後 is a phrase listing 'before and after' as separate concepts. Use 前後 for approximate time, and 前と後 for explicit before-and-after sequences.
