האופטומטריסט בודק את האישון.

ה־ is the Hebrew definite article, equivalent to English the.

So:

• האופטומטריסט = the optometrist
• האישון = the pupil

Hebrew attaches the directly to the noun as a prefix, instead of writing it as a separate word.

את marks a definite direct object. It usually has no separate English translation.

In this sentence:

• בודק = checks / is checking
• את האישון = the pupil as the thing being checked

Because האישון is definite (the pupil), Hebrew uses את before it.

A very common pattern is:

subject + verb + את + definite object

For example:

• הילד אוכל את התפוח = The boy eats the apple
• הרופא בודק את העין = The doctor examines the eye

בודק is the masculine singular present-tense form of the verb לבדוק, meaning to check / examine.

Its root is ב־ד־ק.

In this sentence, it matches the subject האופטומטריסט, which is treated as masculine singular here.

A few related forms are:

• בודק = masculine singular
• בודקת = feminine singular
• בודקים = masculine plural / mixed plural
• בודקות = feminine plural

It can mean either one, depending on context.

Hebrew present tense often covers both:

• The optometrist checks the pupil
• The optometrist is checking the pupil

If there is no extra context, English can translate it either way.

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

So Hebrew says:

• האופטומטריסט בודק את האישון

Literally, the sentence already contains the main action checks / is checking, so no extra present-tense is is needed.

This is normal in Hebrew. English requires is in forms like is checking, but Hebrew does not.

Yes. אישון here means the pupil of the eye.

That is important because English pupil has two meanings:

• a student
• the dark center of the eye

Hebrew uses different words for these meanings:

• אישון = pupil of the eye
• תלמיד / תלמידה = student

So in this sentence, האישון can only mean the eye’s pupil.

Yes. As written, the verb is masculine singular: בודק.

If the optometrist were female, Hebrew would normally change both the noun and the verb:

• האופטומטריסטית בודקת את האישון

That means The female optometrist checks/is checking the pupil.

So the change is:

• האופטומטריסט → האופטומטריסטית
• בודק → בודקת

No, it is a borrowed word based on the international term optometrist.

Hebrew uses many borrowed professional terms, especially in medicine and science.

Even though the word is borrowed, it still behaves like a Hebrew noun in the sentence. For example, it can take the definite article:

• אופטומטריסט = optometrist
• האופטומטריסט = the optometrist

The normal, neutral word order here is:

subject + verb + object

So:

• האופטומטריסט = subject
• בודק = verb
• את האישון = object

This is very natural Hebrew.

Because את marks the object, Hebrew can sometimes change the order for emphasis, but the version you have is the most straightforward and standard one for learners.

A rough pronunciation is:

ha-optometrist bo-DEK et ha-ee-SHON

More word by word:

• האופטומטריסט = ha-optometrist
• בודק = bo-DEK
• את = et
• האישון = ha-ee-SHON

The stress is usually near the end in בודק and אישון.

The plurals are:

• אופטומטריסט → אופטומטריסטים = optometrists
• אישון → אישונים = pupils

With the definite article:

• האופטומטריסטים = the optometrists
• האישונים = the pupils

So a plural version of the sentence could be:

• האופטומטריסטים בודקים את האישונים
  The optometrists check the pupils
