אני כותבת עוד משפט במחברת ובודקת אם התרגום שלי נכון.

Because the speaker is feminine singular: אני = I, and the verb forms match a female speaker in the present tense.

• אני כותבת = I write / I am writing said by a woman
• אני בודקת = I check / I am checking said by a woman

If the speaker were male, you would usually say:

• אני כותב
• אני בודק

Often, yes, Hebrew can leave it out.

You could say:

• כותבת עוד משפט במחברת ובודקת אם התרגום שלי נכון.

That still means I am writing another sentence in the notebook and checking whether my translation is correct, because the verb forms already tell you the subject is I.

Including אני is still completely natural. It can add clarity, emphasis, or simply sound more explicit.

It can mean both.

Hebrew present tense often covers both:

• simple present: I write
• present progressive: I am writing

So אני כותבת... ובודקת... can mean either:

• I write ... and check ...
• I am writing ... and checking ...

Context tells you which sounds more natural in English.

Here, עוד means another, one more, or an additional.

So:

• עוד משפט = another sentence / one more sentence

In other contexts, עוד can also mean still, more, or yet, but here it clearly means another / one more.

Because משפט here is indefinite: another sentence, not another specific sentence.

• משפט = a sentence
• המשפט = the sentence

So:

• עוד משפט = another sentence
• עוד המשפט would usually not fit this meaning

The sentence is talking about writing one more sentence, not a specifically identified one.

במחברת means in the notebook.

It is made from:

• ב־ = in
• מחברת = notebook
• with the definite article ה built in: ב + ה + מחברת

So conceptually:

• במחברת = in the notebook

This is a very common Hebrew pattern: prepositions like ב־, ל־, and כ־ often combine with ה.

For example:

• בבית = in the house
• לילד = to the boy
• כמלך = as the king

מחברת is a feminine noun. You can often tell because many feminine nouns end in ־ת or ־ה, though not always.

Here it matters mainly for grammar in other contexts, such as adjectives and pronouns. In this sentence, the main point is just that במחברת means in the notebook.

For example:

• מחברת חדשה = a new notebook
• המחברת שלי = my notebook

The adjective חדשה is feminine because מחברת is feminine.

The ו means and.

So:

• כותבת ... ובודקת ... = writing ... and checking ...

Hebrew often uses one subject with two connected verbs, just like English:

• אני כותבת ... ובודקת ...
• I am writing ... and checking ...

The subject אני applies to both verbs.

Because in present-tense Hebrew, the verb to be is usually omitted.

So Hebrew says:

• התרגום שלי נכון

Literally, that is something like:

• my translation correct

But it means:

• my translation is correct

This is completely normal in Hebrew. In the present tense, nominal sentences usually do not use a separate word for is / am / are.

Here אם means whether.

After a verb like בודקת (checking), Hebrew commonly uses אם to introduce an indirect yes/no question:

• בודקת אם התרגום שלי נכון
• checking whether my translation is correct

In English, if and whether can both appear in some cases, but whether is often the more precise translation here.

Because my translation is definite. In Hebrew, a noun followed by שלי is usually definite, so the noun normally takes ה־:

• התרגום שלי = my translation

This is the usual everyday pattern:

• הספר שלי = my book
• המחברת שלי = my notebook
• החבר שלי = my friend

Saying תרגום שלי without ה is generally not the normal neutral form here.

שלי means my.

Hebrew often expresses possession with:

• noun + של + pronoun

So:

• התרגום שלי = my translation
• literally: the translation of me

This structure is very common in modern Hebrew.

Some examples:

• הבית שלי = my house
• המורה שלי = my teacher
• הרעיון שלי = my idea

Because it agrees with התרגום, and תרגום is a masculine singular noun.

So:

• התרגום שלי נכון = my translation is correct

If the noun were feminine, the adjective would usually be feminine too:

• התשובה שלי נכונה = my answer is correct

So the adjective changes according to the noun it describes.

It can mean more than one thing.

Common meanings include:

• sentence in language
• law / legal judgment / trial-related sense in legal contexts

But in this sentence, because of כותבת עוד משפט, the meaning is clearly sentence in the language sense.

Context usually makes the meaning obvious.

It could do either, depending on context.

Because Hebrew present tense is broad, the sentence can describe:

• something happening right now: I am writing another sentence...
• a repeated or habitual action: I write another sentence... and check...

Without more context, both are grammatically possible. English usually forces you to choose more clearly than Hebrew does.
