גם אמא שרה יפה.

A simple pronunciation guide is:

gam ima shara yafe

More roughly:

• גם = gam
• אמא = iMA
• שרה = shaRA
• יפה = yaFE

The stress is usually on the last syllable in אמא, שרה, and יפה.

גם means also or too.

In this sentence, it means something like:

Mom also sings beautifully
or
Mom sings beautifully too

Hebrew often puts גם right before the word or idea it is adding emphasis to. Here, starting the sentence with גם makes אמא feel like the thing being added: Mom too.

It can mean mom or mother, depending on context.

In everyday Hebrew, אמא is very often used the way English speakers say Mom. It can also imply my mom even without שלי.

So:

• אמא = mom / mother
• אמא שלי = my mom explicitly

Hebrew often leaves this kind of relationship understood from context.

Because unpointed Hebrew often has words that look identical in writing.

שרה can be:

• the name Sarah
• a verb form from לשיר = to sing

In this sentence, context tells you it is the verb, not the name.

That is very common in Hebrew: you often need the sentence context, not just the spelling, to know which word you are looking at.

It can actually mean either, depending on context.

With this spelling, שרה may be:

• sings / is singing (feminine singular present)
• sang (third person feminine singular past)

So the sentence by itself can be ambiguous. Context usually clears it up.

For example:

• עכשיו אמא שרה יפה = Now Mom is singing beautifully
• אתמול אמא שרה יפה = Yesterday Mom sang beautifully

Since the learner already has the meaning shown, here you should read it as sings.

Because the subject אמא is feminine.

Hebrew verbs often agree with the subject in gender and number. Since אמא is feminine singular, the verb appears in the feminine singular form.

Compare:

• אבא שר יפה = Dad sings beautifully
• אמא שרה יפה = Mom sings beautifully

So the extra ה in שרה is part of the feminine form.

Because Hebrew often uses an adjective in a way that English would translate as an adverb.

Literally, יפה means beautiful / pretty / nice.
But after a verb, it often works like beautifully, nicely, or sometimes even well.

So:

• היא יפה = She is beautiful
• היא שרה יפה = She sings beautifully

This is very normal Hebrew.

Yes, but the emphasis can change.

For example:

• גם אמא שרה יפה = Mom sings beautifully too
• אמא גם שרה יפה = often feels more like Mom also sings beautifully
  (for example, in addition to doing something else)

Hebrew word order is somewhat flexible, but moving גם changes what sounds emphasized. In your sentence, starting with גם naturally highlights Mom too.

No. The sentence already has a real verb: שרה = sings / sang.

So this is not a sentence like Mom is beautiful. It is a sentence with an action:

• subject: אמא
• verb: שרה
• manner: יפה

In other words, the structure is:

also + Mom + sings + beautifully
