À force de relire la photocopie, je vois enfin l’erreur dans mon adresse.

À force de + infinitive means something like by doing something over and over, through repeated effort, or after doing something so much.

So:

• À force de relire la photocopie... = By rereading the photocopy again and again... = After rereading the photocopy so many times...

This expression often suggests that repetition eventually produces a result.

Because à force de is a fixed expression. It is followed by:

• a noun: à force de patience
• or an infinitive: à force de chercher, à force de relire

So de is required here. You should learn à force de as a whole chunk.

Lire means to read.
Relire means to read again or to reread.

The prefix re- often adds the idea of again:

• faire = to do

• refaire = to do again

• lire = to read
• relire = to reread

So relire la photocopie means the speaker has already read it before and is reading it again.

La photocopie refers to a specific photocopy, one that is already known from the context.

Compare:

• une photocopie = a photocopy, any photocopy, introducing it for the first time
• la photocopie = the photocopy, a particular one

In this sentence, the speaker is talking about one specific photocopy they have been checking.

French often uses the present tense to describe a result that is happening now:

• je vois enfin l’erreur = I finally see the mistake

The sentence focuses on the moment of realization. After all that rereading, the speaker now sees the error.

English might also say I finally see the mistake, so the present tense works naturally in both languages here.

Enfin means finally.

It shows that the result happened after some time or effort:

• je vois enfin l’erreur = I finally see the mistake

Its position is very natural here: it comes before the thing that is finally happening.

In French, nouns usually need an article much more often than in English.

So where English can say:

• I see an error
• I see the error

French usually needs:

• je vois une erreur
• je vois l’erreur

Here, l’erreur means the error, probably a specific mistake in the address that the speaker has now spotted.

Also, le becomes l’ before a vowel sound:

• le erreur ❌
• l’erreur ✅

Using l’erreur suggests a specific error, not just any mistake.

• je vois une erreur = I see an error / one error
• je vois l’erreur = I see the error

In this sentence, the speaker has probably been looking for the particular mistake in the address, and now they have found it.

Dans mon adresse means in my address.

Here adresse usually means a postal or written address, such as:

• a street address
• the address written on a form or envelope

So the error is located inside the written address itself.

Depending on context, adresse can also mean other kinds of address, but in this sentence the most natural meaning is a postal/contact address.

Because the idea is that the mistake is inside the written address.

• l’erreur dans mon adresse = the error in my address

This is a very normal use of dans when talking about something contained in a text, list, form, document, or piece of writing.

For example:

• une faute dans ce texte = a mistake in this text
• une erreur dans mon nom = an error in my name

The comma separates the introductory phrase from the main clause:

• À force de relire la photocopie, = introductory cause/background
• je vois enfin l’erreur dans mon adresse. = main statement

It helps the sentence read more clearly. In English, you would often punctuate it similarly:

• After rereading the photocopy so many times, I finally see the error in my address.

No. It is neutral by itself, but it often implies repetition, persistence, or sometimes even exasperation.

Examples:

• À force d’essayer, il a réussi.
  By trying again and again, he succeeded.

• À force de crier, tu vas perdre ta voix.
  If you keep shouting so much, you’ll lose your voice.

So in your sentence, it suggests repeated rereading that eventually leads to success.

Yes. Even if the meaning is already clear, several English versions are natural:

• By rereading the photocopy over and over, I finally see the mistake in my address.
• After rereading the photocopy so many times, I finally spot the error in my address.
• From reading the photocopy again and again, I finally notice the mistake in my address.

The French sentence keeps the emphasis on repetition leading to the discovery.

Photocopie is a normal word and usually means photocopy or copy made by a copier.

In many real-life situations, French speakers might also say:

• une copie
• le document
• la feuille

depending on context.

But la photocopie is perfectly correct and clearly means the speaker is looking at a copied document.

It is often very similar, but context matters.

Adresse can mean:

• a street/postal address
• an email address
• sometimes skill or dexterity in other contexts

In your sentence, because of l’erreur dans mon adresse, the most likely meaning is the written contact address on the photocopy.

So yes, it corresponds closely to English address here.
