Je vois une rayure ici.

Because voir is the infinitive, meaning to see. After the subject je, French normally needs a conjugated verb, so voir becomes vois.

• voir = to see
• je vois = I see

This is the present-tense je form of voir.

It is the present tense.

So je vois une rayure ici means I see a scratch here or I can see a scratch here, depending on context. French often uses the simple present where English might sometimes use can see.

A simple guide is:

• je sounds like zhuh
• vois sounds roughly like vwah

So je vois is approximately zhuh vwah.

A few useful pronunciation notes:

• The s in vois is silent.
• The j in je is the soft sound heard in measure.
• In careful speech, je is fully pronounced, but in fast spoken French it may sound more like j’vois.

Because rayure is a feminine noun. In French, nouns have grammatical gender, so the article must match:

• un for masculine nouns
• une for feminine nouns

Since rayure is feminine, you say une rayure.

Rayure can mean several related things depending on context:

• scratch on a surface
• mark
• stripe
• streak

In a sentence like Je vois une rayure ici, it often means a scratch or visible line/mark on something, such as a car, a table, glasses, or a screen.

So even if the meaning has already been given, it is useful to know that rayure is a context-dependent word.

French usually requires an article before a singular countable noun. So where English says a scratch, French says une rayure.

You generally cannot say just Je vois rayure ici. That would sound ungrammatical.

Because French often places adverbs of place like ici after the main object.

So this word order is very natural:

• Je vois une rayure ici.

It means I see a scratch here.

You may sometimes hear other word orders, but this version is the most straightforward and natural for a learner.

Both can relate to here/there, but they are used a little differently.

• ici = here, more specifically
• là = often there, but in everyday speech it can also mean here depending on context

So ici is a clear choice when you want to say here in a precise way.
In conversation, a French speaker might also say Je vois une rayure là while pointing.

In standard French, yes, you need the subject pronoun.

French verbs usually require an expressed subject:

• Je vois = correct
• Vois une rayure ici = not a normal complete statement

Unlike Spanish or Italian, French usually does not drop subject pronouns in ordinary sentences.

Normally, no important liaison is made in this sentence.

For example:

• vois une: no usual liaison
• rayure ici: no liaison

So you can pronounce the words separately in a natural way. That makes this sentence relatively easy to say.

A few common ways are:

• Tu vois une rayure ici ? = Do you see a scratch here?
• Est-ce que tu vois une rayure ici ?
• Vois-tu une rayure ici ? = more formal

If you want to keep the same subject I, you could ask:

• Est-ce que je vois une rayure ici ? = Am I seeing a scratch here? / Do I see a scratch here?

You put ne ... pas around the conjugated verb:

• Je ne vois pas de rayure ici.

Notice an important change:

• une rayure becomes de rayure

That is the usual pattern after negation with an indefinite article.

So:

• Je vois une rayure ici. = I see a scratch here.
• Je ne vois pas de rayure ici. = I do not see a scratch here.
