היא צעירה ממני.

A simple pronunciation guide is:

hee tseh-ee-RA mi-MEH-nee

A more Hebrew-style transliteration is:

hi tze'ira mimeni

A couple of helpful notes:

• היא is pronounced hee, not like two separate syllables.
• צעירה has three syllables: tzeh-ee-ra.
• ממני means than me / from me, depending on context.

Because היא means she, and Hebrew adjectives must agree with the noun or pronoun they describe in gender and number.

So:

• היא צעירה = she is young
• הוא צעיר = he is young

Here, the subject is feminine singular, so the adjective is also feminine singular: צעירה.

In Hebrew, the verb to be is usually not stated in the present tense.

So instead of saying something like She is young, Hebrew simply says:

היא צעירה

The same thing happens in your sentence:

היא צעירה ממני

In past or future, Hebrew does use forms of to be, for example:

• היא הייתה צעירה ממני = she was younger than me
• היא תהיה צעירה ממני = she will be younger than me

Hebrew often makes comparisons by using:

adjective + מ־ / מן + thing being compared

So literally, this sentence is built like:

she + young + than me

That is why צעירה can mean young, but in this structure it is understood as younger.

This is very common in Hebrew:

• הוא גבוה ממני = he is taller than me
• היא חכמה ממני = she is smarter than me

So Hebrew does not need a special -er ending the way English does.

ממני is the form of מ־ / מן used with אני.

It literally comes from the idea of from me, but in comparisons it means than me.

So:

• ממני can mean from me
• in a sentence like this, it means than me

This is very normal in Hebrew. The same basic word מ־ is used in several related ways.

No. ממני stays the same whether the speaker is male or female.

So both a man and a woman can say:

היא צעירה ממני

What changes in Hebrew is usually the form of adjectives, verbs, or pronouns that agree with the subject, not this pronoun form for me.

Sometimes, yes.

If the context is already clear, a Hebrew speaker might just say:

צעירה ממני

That can mean younger than me.

But as a full, clear sentence, especially for a learner, היא צעירה ממני is the safest form.

So:

• היא צעירה ממני = full sentence
• צעירה ממני = possible in context, but less explicit

The adjective would change to match the subject.

Examples:

• הוא צעיר ממני = he is younger than me
• הן צעירות ממני = they (feminine) are younger than me
• הם צעירים ממני = they (masculine/mixed) are younger than me

Notice that ממני does not change here. The part that changes is צעיר / צעירה / צעירים / צעירות.

Yes, you may hear that, and it will be understood.

But היא צעירה ממני is already a complete and natural way to say she is younger than me.

For a learner, the important point is:

• צעירה ממני is correct and natural
• יותר צעירה ממני may also appear in real speech, but the shorter form is very common for this idea

So if your goal is clean, standard beginner Hebrew, היא צעירה ממני is excellent.

Then you replace ממני with a form using מ־ before the other person or thing.

For example:

• היא צעירה מדנה = she is younger than Dana
• היא צעירה מאחותה = she is younger than her sister
• היא צעירה ממנו = she is younger than him
• היא צעירה ממנה = she is younger than her

So ממני is just the me version of a larger comparison pattern.
