امروز نان ندارم.

A common pronunciation is:

• emruz nân nadâram Roughly: em-ROOZ NAAN na-DAA-ram (stress varies by speaker).
  Notes: â is a long a sound (like father), and ن is n.

امروز means today. It’s a time adverb, and it’s flexible:

• امروز نان ندارم. (Today I don’t have bread.)
• نان ندارم امروز. (I don’t have bread today.)
  The first is more neutral/common.

It’s one written word but it contains parts:

• نـ = negation (not)
• دار = verb stem from داشتن (to have)
• ـم = I ending
  So ندارم literally = I don’t have.

Usually no. The verb ending ـم already shows it’s I:

• (من) امروز نان ندارم.
  Adding من is possible for emphasis or contrast (like “I don’t have bread (but someone else might)”).

Persian doesn’t have a/an or the the same way English does. A bare noun like نان can mean:

• bread in general
• some bread
• the bread (from context)
  If you want to be more specific, Persian uses other tools (like این “this”, or یک “one/a”).

A common way is to add هیچ:

• امروز هیچ نان ندارم. = I don’t have any bread today.
  You may also hear اصلاً for “at all”:
• امروز اصلاً نان ندارم.

Here it’s just the general noun bread (often treated like an uncountable).
Plural can be:

• نان‌ها = breads / loaves (context-dependent)
  But in everyday speech you usually keep it singular unless you really mean different breads/loaves.

The base verb is داشتن (to have). Present tense negative forms:

• ندارم = I don’t have
• نداری = you (sg.) don’t have
• ندارد = he/she/it doesn’t have
• نداریم = we don’t have
• ندارید = you (pl./formal) don’t have
• ندارند = they don’t have

Yes, depending on context. نان ندارم can imply you have none available at home / on you / in your possession. If you want to explicitly mean “we ran out,” you can say:

• امروز نان‌مان تمام شده. = Our bread is finished / we’ve run out of bread.

Common ways:

• امروز نان داری؟ = Do you have bread today?
• امروز نان نداری؟ = Don’t you have bread today? / You don’t have bread today?
  In speech, rising intonation often signals it’s a question.

ندارم = I don’t have (possession).
نیست = there isn’t / it isn’t (existence).
So:

• امروز نان ندارم. = I don’t have bread (in my possession).
• امروز نان نیست. = There is no bread (available / existing here), more general and not necessarily about you.

Not normally in this sentence. را marks a specific direct object, and with “have” + an indefinite/general noun, it’s usually omitted:

• Natural: امروز نان ندارم. If you mean a specific bread (e.g., a particular loaf you expected), then را becomes more possible, but the sentence would usually need context or additional words (like این نان را ندارم = I don’t have this bread).

One natural contrast structure is:

• امروز نان ندارم، ولی برنج دارم.
  You can also use اما instead of ولی (both mean “but”).
