تبدأ الوردية الآن.

Because الوردية is a feminine singular noun, and the verb agrees with it.

• تبدأ = she/it starts (feminine singular)
• يبدأ = he/it starts (masculine singular)

In Arabic, many non-human and abstract nouns still have grammatical gender. وردية is grammatically feminine, so the verb is feminine too.

الوردية means the shift, usually a work shift.

It comes from وردية = a shift and الـ makes it definite:

• وردية = a shift
• الوردية = the shift

So this sentence is talking about a specific shift already known from context.

Because Arabic verbs already include the subject information.

تبدأ by itself already tells you:

• third person
• singular
• feminine

So Arabic does not need a separate word for it here. The noun الوردية is the subject, and the verb form already matches it.

A very literal breakdown would be:

• تبدأ = starts
• الوردية = the shift
• الآن = now

Because this is a very common Arabic sentence pattern called a verbal sentence.

Arabic often uses:

• verb + subject + other information

So:

• تبدأ الوردية الآن = The shift starts now

You can also say:

• الوردية تبدأ الآن

That is also correct, but it is a nominal sentence structure and can sound slightly different in emphasis. In many contexts, both are natural.

It is the imperfect form, which is often used for the present or future, depending on context.

Here, because of الآن (now), it clearly means a present-time action:

• تبدأ الآن = starts now / is starting now

So although Arabic grammar calls this form the imperfect, in this sentence it is best understood as present time.

It is pronounced approximately tabdaʾu in full formal pronunciation.

A few important points:

• تـ = ta
• بدأ contains a hamza (ء), a glottal stop
• In careful MSA, the ending may be pronounced -u

So in full pronunciation:

• تبدأُ = tabdaʾu

In pause or less formal reading, learners often hear something closer to:

• tabdaʾ

The hamza is important. Without it, the word would sound different.

That final ة is called taa marbuuTa (ة), and it often marks a noun as feminine.

So:

• وردية is feminine
• therefore the verb is feminine too: تبدأ

In pause, ة is usually pronounced like -a:

• الوردية ≈ al-wirdiyya or al-wardiyya, depending on pronunciation tradition

But in some grammatical contexts, especially when endings are pronounced, it can sound like -t.

الآن means now.

It functions as an adverb of time, telling you when the action happens.

So:

• تبدأ الوردية الآن = The shift starts now

Its position here is very natural. Arabic word order is somewhat flexible, but placing الآن at the end is common and clear.

Yes, in fully vocalized formal Arabic, the sentence would usually be written something like:

• تبدأُ الورديةُ الآنَ

These endings show grammar:

• تبدأُ: verb ending
• الورديةُ: subject in the nominative
• الآنَ: adverb with its usual ending

However, in normal Arabic writing, these short vowels are usually not written, so you see:

• تبدأ الوردية الآن

Learners should know the endings exist, even though they are often omitted in everyday text.

Yes. In English, the best translation depends on context.

Because the Arabic imperfect can be flexible, تبدأ الوردية الآن can be understood as:

• The shift starts now
• The shift is starting now
• The shift begins now

All of these are reasonable depending on the situation.

A simple negation is:

• لا تبدأ الوردية الآن

This means:

• The shift does not start now or
• The shift is not starting now

Here لا negates the present/imperfect verb.

So:

• تبدأ الوردية الآن = The shift starts now
• لا تبدأ الوردية الآن = The shift does not start now
