همکارم گفت که فایل دیگر را ندیده است و باید دوباره آن را چاپ کنیم.

A natural pronunciation is:

hamkâram goft ke fâyl-e digar râ nadide ast va bâyad dobare ân râ châp konim

A more natural spoken version may sound a bit smoother, like:

hamkâram goft ke fây-le digaro nadide ast o bâyad dobare ân-o châp konim

A few pronunciation notes:

• همکارم → hamkâram
• فایل دیگر is pronounced fâyl-e digar
  There is an ezafe sound, even though it is not written here.
• را in careful speech is râ, but in conversation it often becomes ro or o
• و is often pronounced va in careful speech, but o in everyday speech

همکارم breaks down as:

• همکار = colleague, coworker
• ـم = my

So همکارم literally means my colleague.

This ـم is a possessive ending. Very common examples are:

• دوستم = my friend
• کتابم = my book
• استادم = my teacher

که means that and introduces the clause that follows said.

So:

• گفت که ... = said that ...

In English, that is often optional. Persian is similar: in casual speech, که can sometimes be omitted, but it is very common and natural to include it.

So this part:

• همکارم گفت که ...

means:

• My colleague said that ...

Here دیگر means other or another.

So:

• فایل دیگر = the other file or another file, depending on context

In this sentence, because the object is marked with را, it is understood as a specific file, so the other file is a good interpretation.

A useful note: دیگر can also mean any more / anymore in other contexts, but not here.

Examples:

• کتاب دیگر = another book / the other book
• مشکل دیگر = another problem / the other problem

There is actually an ezafe connection here, but after many consonant-ending words it is usually not written.

So:

• written: فایل دیگر
• pronounced: fâyl-e digar

That -e sound links the noun to what follows it.

This is very common in Persian. For example:

• کتاب خوب is pronounced ketâb-e xub
• مرد جوان is pronounced mard-e javân

So even though you do not see anything written between فایل and دیگر, you still pronounce an ezafe.

را marks a specific direct object.

So:

• فایل دیگر را = the other file as a definite object
• آن را = it, again as a definite object

In this sentence, both objects are specific:

1. فایل دیگر را ندیده است
   He/she has not seen the other file

2. آن را چاپ کنیم
   We should print it

So the two را markers are completely normal.

In everyday spoken Persian, را is often pronounced ro:

• فایل دیگر رو
• آن رو

Because آن means that or it, and here it refers back to the other file.

So the sentence first mentions the file explicitly, then refers to it again with a pronoun:

• فایل دیگر را = the other file
• آن را = it

This avoids repeating the full noun phrase again.

A very common alternative in more conversational Persian would be:

• چاپش کنیم

where ـش means it / him / her depending on context.

So instead of آن را چاپ کنیم, a speaker might say:

• چاپش کنیم = print it

ندیده است is the present perfect negative form of دیدن.

It is built like this:

• دیده = seen
• است = is/has
• ندیده است = has not seen

In Persian, this form is often used where English might use:

• has not seen
• had not seen

depending on context.

Because the main verb is گفت = said, English often translates this naturally as had not seen:

• My colleague said that he/she had not seen the other file

So even though the Persian form is literally present perfect, in context it can match English past perfect very naturally.

It comes from the verb دیدن = to see.

Formation:

• past participle: دیده = seen
• add negative prefix: ندیده = not seen
• add است: ندیده است = has not seen

So the pattern is:

• past participle + است for present perfect
• نـ + past participle + است for negative present perfect

Other examples:

• رفته است = has gone
• نرفته است = has not gone
• خورده است = has eaten
• نخورده است = has not eaten

After باید, Persian normally uses a subjunctive-style present form, not a plain indicative می‌ form.

So:

• باید چاپ کنیم = we must/should print
• چاپ می‌کنیم = we print / we are printing / we will print, depending on context

In other words:

• باید expresses necessity
• the verb after it takes the appropriate non-می form

Because چاپ کردن is a compound verb, the part that changes is کردن:

• باید چاپ کنم = I must print
• باید چاپ کنیم = we must print
• باید چاپ کند = he/she must print

Because چاپ کردن is a compound verb.

It consists of:

• چاپ = print, printing
• کردن = to do

Together:

• چاپ کردن = to print

Many Persian verbs work this way. The main meaning is often in a noun-like element, and کردن carries the verb inflection.

So here:

• چاپ کنیم = we print / we should print

Other common compound verbs:

• کار کردن = to work
• فکر کردن = to think
• تمیز کردن = to clean

دوباره means again.

In this sentence:

• باید دوباره آن را چاپ کنیم
• we should print it again

It comes before the object pronoun phrase آن را, which is a very natural position in Persian.

You may also hear slightly different word orders, such as:

• باید آن را دوباره چاپ کنیم

That also works. Persian word order can be somewhat flexible, but the original version is perfectly natural.

Persian is generally Subject-Object-Verb, and verbs often come at the end of their clause.

Here is the structure:

• همکارم = subject
• گفت = said
• که = that
• فایل دیگر را = the other file
• ندیده است = has not seen
• و = and
• باید دوباره آن را چاپ کنیم = we should print it again

So the sentence is basically:

• My colleague said
• that he/she has not seen the other file
• and that we should print it again

Notice that in both subordinate parts, the verb comes late:

• فایل دیگر را ندیده است
• آن را چاپ کنیم

That is very typical Persian structure.

No, it is not explicitly stated in that clause.

In Persian, subject pronouns are often omitted when they are understood from context.

So ندیده است means:

• he/she has not seen

The sentence does not specify he or she because Persian third-person singular does not mark gender.

From context, we understand that it refers to my colleague.

So:

• همکارم گفت که فایل دیگر را ندیده است
• My colleague said that he/she had not seen the other file

It can often be translated as either must, should, or have to, depending on context and tone.

So:

• باید دوباره آن را چاپ کنیم

could be understood as:

• we must print it again
• we should print it again
• we have to print it again

If the context is practical and matter-of-fact, English often uses have to or need to. If it sounds like an obligation, must works well. If it sounds more like a recommendation, should works.

So باید is a very flexible necessity word.
