faururain no mae de tomaru.

It is read:

ファウルラインのまえでとまる。

Word by word:

• ファウルライン = fauru rain
• 前 = まえ
• 止まる = とまる

In normal Japanese writing, it would usually appear without spaces:

ファウルラインの前で止まる。

Because it is a loanword from English: foul line.

Katakana is commonly used for:

• foreign loanwords
• foreign names
• sound effects
• words the writer wants to make stand out

So ファウルライン is just the Japanese way of writing the English-based term foul line.

の connects nouns.

Here, it links:

• ファウルライン
• 前

So ファウルラインの前 means literally something like:

• the front of the foul line
• or more naturally, in front of the foul line

This is a very common pattern:

• 学校の前 = in front of the school
• 駅の前 = in front of the station
• 家の前 = in front of the house

前 can mean either:

• front / in front of in a physical sense
• before in a time sense

Here it is the physical meaning: in front of.

So this is a location expression, not a time expression.

Examples:

• 駅の前 = in front of the station
• 食事の前 = before a meal

Same word, different meaning depending on context.

で marks the place where an action or event happens.

In this sentence, the action/event is 止まる = to stop.

So ファウルラインの前で means that the stopping happens at/in front of the foul line.

A helpful breakdown is:

• ファウルラインの前 = in front of the foul line
• ファウルラインの前で止まる = stop in front of the foul line

Yes, ファウルラインの前に止まる is also natural Japanese.

The difference is small and often not important for beginners, but a rough guide is:

• で focuses on the place where the event happens
• に often focuses more on the point/location reached as a result

So:

• 前で止まる = stop at/in front of it
• 前に止まる = come to a stop in front of it

In many everyday situations, both are acceptable.

This is an important pair:

• 止まる = to stop (intransitive)
• 止める = to stop something (transitive)

So:

• 車が止まる = the car stops
• 車を止める = stop the car

In your sentence, the thing is stopping by itself grammatically, so Japanese uses 止まる.

If you changed it to 止める, you would need a direct object:

• 車をファウルラインの前で止める = stop the car in front of the foul line

It is the plain dictionary form, also called the non-past form.

This form can mean different things depending on context, such as:

• a general statement
• a habitual action
• a description in instructions, captions, or diagrams
• future action in some contexts

So by itself, 止まる is neutral and unspecific. It does not automatically mean only present tense.

If this were a direct command, Japanese would use something else, for example:

• 止まれ = Stop!
• 止まってください = Please stop.

The subject is omitted.

Japanese often leaves out the subject when it is obvious from context. So the sentence does not explicitly say:

• who stops
• what stops

Depending on the situation, it could mean something like:

• the ball stops
• the player stops
• the car stops
• you stop

Japanese does this very often, much more than English.

Because Japanese normally follows SOV word order, where the verb comes at or near the end.

English often uses Subject + Verb + Object/other information, but Japanese usually places the main verb last.

So the structure here is roughly:

• location phrase: ファウルラインの前で
• verb: 止まる

This verb-final pattern is one of the most basic features of Japanese sentence structure.

Those spaces are probably added for readability or for learners.

Standard Japanese usually does not use spaces between words, so the normal written form is:

ファウルラインの前で止まる。

You will often see spaces in:

• beginner materials
• subtitles for children
• language-learning examples
• some digital interfaces

So the spaces are not part of the grammar. They are just a reading aid.
