その means that and points to a specific word already mentioned or understood from context.

So その言葉 means that word.

Japanese often uses:

• この = this ... near the speaker
• その = that ... near the listener or already mentioned
• あの = that ... over there / farther away

In this sentence, その helps identify which word was searched.

The particle を marks the direct object of the verb.

Here, the verb is 検索した = searched / looked up, so the thing being searched is その言葉.

• その言葉を検索した = searched that word

In English, we might say search for that word, but in Japanese the word itself is directly marked as the object with を.

The particle で often marks the place, method, or means by which something is done.

Here, ネットで means on the internet or using the internet.

So:

• ネットで検索した = searched on the internet

This で is not marking location in the sense of simple existence; it marks the medium/tool used for the action.

検索したら is the -たら form of 検索した.

It can mean:

• when I searched
• after searching
• if you search
  depending on context.

In this sentence, it most naturally means:

• When I searched that word on the internet, ...
• After searching that word on the internet, ...

The -たら form often connects one event to the result that followed.

So the structure is:

• その言葉をネットで検索したら、Xが見つかった。
• When I searched that word online, I found X.

The comma separates the first clause from the result clause.

The sentence has this basic shape:

• [When I searched that word online], [an easy-to-understand explanatory link was found].

Japanese commas are often used more flexibly than English commas, but here it helps show the pause between:

1. the condition/time clause
2. the main result

It makes the sentence easier to read.

分かりやすい means easy to understand.

It is made from:

• 分かる = to understand
• やすい = easy to do

So literally it is something like easy to understand.

Examples:

• 読みやすい = easy to read
• 使いやすい = easy to use
• 分かりやすい説明 = an easy-to-understand explanation

Even though 分かる is not exactly the same as English understand in grammar, 分かりやすい is a very common and natural expression.

分かりやすい説明のリンク means:

• a link to an easy-to-understand explanation

The adjective 分かりやすい modifies 説明, not リンク.

So the structure is:

• 分かりやすい = easy to understand
• 説明 = explanation
• 説明のリンク = link for/to the explanation

If you said 分かりやすいリンク, that would mean an easy-to-understand link, which is not very natural, because a link itself is not usually described as understandable. The explanation is what is easy to understand.

The particle の connects nouns. It has many possible relationships, not just possession.

Here, 説明のリンク means something like:

• a link to an explanation
• an explanation link

The exact relationship is understood from context.

So AのB can mean many things, such as:

• B of A
• B for A
• B related to A
• B about A

In this sentence, 説明のリンク is best understood as a link to an explanation.

The particle が marks the subject of the verb 見つかった.

So:

• リンクが見つかった = a link was found / I found a link

The important thing here is that the sentence is presenting a link as the thing that turned up.

This is very natural with verbs like:

• 見つかる = be found / turn up
• ある = exist / there is
• 起こる = happen

So が is used because the link is the thing that was found.

This is a very common learner question.

• 見つけた = found it / found something
  → transitive, someone actively found something
• 見つかった = was found / turned up
  → intransitive, focuses on the thing appearing or being found

Compare:

• リンクを見つけた = I found a link
• リンクが見つかった = a link was found / I came across a link

In this sentence, 見つかった sounds natural because it emphasizes the result: a useful link turned up as a consequence of searching.

It feels a bit less direct and often more natural in Japanese than explicitly saying I found.

Not exactly. It may look passive in English translation, but grammatically it is usually treated as the intransitive counterpart of 見つける.

The pair is:

• 見つける = to find something
• 見つかる = to be found / to turn up

So 見つかった is the past form of 見つかる, not the passive of 見つける.

That is why the particles differ:

• リンクを見つけた
• リンクが見つかった

Japanese often omits the subject when it is obvious from context.

In this sentence, the person searching is understood from the situation, and in English it would often be translated as I:

• When I searched that word online, I found a link to an easy-to-understand explanation.

But Japanese does not need to say 私は unless there is a reason to emphasize it or contrast it with someone else.

This omission is extremely common and natural.

Yes, ネット is a common shortened form of インターネット.

So:

• ネットで検索する = search online
• インターネットで検索する = search on the internet

ネット is very common in everyday Japanese and sounds natural here.
インターネット is a bit more formal or full-length.

You might also see:

• ネット検索する = do an internet search
• ググる = google it, very casual

The sentence breaks down like this:

• その言葉を = that word + object marker
• ネットで = on the internet
• 検索したら = when/after searching
• 分かりやすい説明のリンクが = a link to an easy-to-understand explanation + subject marker
• 見つかった = was found / turned up

A natural full understanding is:

• When I searched that word on the internet, I found a link to an easy-to-understand explanation.

Japanese often builds sentences by giving background first, then the main result at the end.

You could translate it that way literally, but it sounds unnatural in English.

A more natural English translation would be:

• When I searched that word online, I found a link to an easy-to-understand explanation.
• After searching that word online, I came across a link with a clear explanation.

This is a good example of how natural English translation may need to change the structure, even though the Japanese uses リンクが見つかった rather than directly saying I found.
