אני כותבת מהר יותר כשיש לי מקלדת טובה ועכבר טוב.

Because כותבת is the feminine singular present-tense form.

Hebrew present-tense verbs agree with the subject in gender and number:

• אני כותבת = I write / I am writing (said by a woman)
• אני כותב = I write / I am writing (said by a man)

So the sentence is being spoken by a female speaker.

It can mean either one, depending on context.

In Hebrew, the present tense often covers both:

• I write
• I am writing

So אני כותבת מהר יותר can mean I write faster or I’m writing faster, depending on the situation.

Yes, להקליד is more specifically to type.

So a more exact sentence could be:

• אני מקלידה מהר יותר... = I type faster...

But לכתוב is often used more broadly, and in a computer context it can sound natural because typing is a way of writing. So the sentence is understandable and natural, even if מקלידה would be more precise.

Hebrew often forms the comparative with יותר = more.

So:

• מהר = fast / quickly
• מהר יותר = more quickly = faster

This is similar to English more quickly, even though the natural English translation is usually faster.

Yes. Both are used.

• מהר יותר = standard and very clear
• יותר מהר = also very common in everyday speech

Both mean faster. A learner should understand both forms.

Because Hebrew often expresses possession with יש + ל־.

Literally:

• יש = there is / there are
• לי = to me

So:

• יש לי literally means there is to me
• but in natural English, that means I have

Therefore:

• כשיש לי = when I have

This is a very important Hebrew pattern:

• יש לי זמן = I have time
• יש לי מחשב = I have a computer

כש means when or sometimes whenever.

So:

• כשיש לי... = when I have...

By contrast:

• אם = if

So these are different:

• כשיש לי מקלדת טובה... = when I have a good keyboard...
• אם יש לי מקלדת טובה... = if I have a good keyboard...

You could also use כאשר, which also means when, but it sounds more formal than כש.

Because adjectives in Hebrew must agree with the noun in gender and number.

• מקלדת is feminine, so: מקלדת טובה
• עכבר is masculine, so: עכבר טוב

This is a basic Hebrew agreement rule:

• masculine singular: טוב
• feminine singular: טובה
• masculine plural: טובים
• feminine plural: טובות

Because in Hebrew, adjectives usually come after the noun they describe.

So:

• מקלדת טובה = keyboard good = good keyboard
• עכבר טוב = mouse good = good mouse

This is the normal Hebrew word order for noun + adjective.

Hebrew usually keeps the adjective with each singular noun in a phrase like this:

• מקלדת טובה ועכבר טוב

That is the clearest and most natural way to say a good keyboard and a good mouse.

If you wanted to describe both nouns together with one adjective, the structure would be different and more complicated, because you would need a plural adjective, and the mixed genders create agreement issues. For learners, repeating the adjective is the safest and most natural pattern here.

Because Hebrew has no separate word for a / an.

So:

• מקלדת can mean a keyboard
• עכבר can mean a mouse

Hebrew only marks the with ה־.

Compare:

• מקלדת טובה = a good keyboard
• המקלדת הטובה = the good keyboard

So the lack of ה־ tells you the nouns are indefinite here.

In Hebrew, ו־ is the word for and, and it is written as a prefix attached to the next word.

So:

• ו = and
• ועכבר = and a mouse / and mouse

This is completely normal in Hebrew spelling.

In this sentence, the context clearly points to typing on a computer, because it mentions:

• מקלדת = keyboard
• עכבר = mouse

So even though כותבת literally comes from to write, here the practical meaning is something like I write/type faster. Context makes that clear.
