הרגש חזק.

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

So Hebrew often says:

הרגש חזק
literally: the feeling strong

but it means:

the feeling is strong

This is very normal in Hebrew.
If you wanted past or future, you would usually include a form of להיות (to be):

• הרגש היה חזק = the feeling was strong
• הרגש יהיה חזק = the feeling will be strong

This is a very important Hebrew pattern.

• הרגש חזק = the feeling is strong
  Here, חזק is the predicate adjective: it describes the subject in a full sentence.

• הרגש החזק = the strong feeling
  Here, חזק is part of a noun phrase, not a complete sentence.

In Hebrew, when an adjective directly modifies a definite noun, the adjective usually also takes ה:

• הספר הגדול = the big book
• הרגש החזק = the strong feeling

But in a sentence like הרגש חזק, the second word is not a definite modifier; it is the description being said about the subject.

Because רגש is a masculine singular noun, and Hebrew adjectives must agree with the noun in gender and number.

So:

• masculine singular: חזק
• feminine singular: חזקה
• masculine plural: חזקים
• feminine plural: חזקות

Since רגש is masculine singular, the correct form is חזק.

For comparison:

• הרגש חזק
• ההרגשה חזקה

Both mean something like the feeling is strong, but the noun is different, so the adjective changes too.

Not exactly.

רגש usually means emotion, feeling, or sentiment, often in a somewhat abstract or literary sense.

הרגשה often means feeling, sensation, or sense, and is very common in everyday speech.

So the difference is often about nuance:

• רגש = emotion / feeling as an inner emotional state
• הרגשה = feeling / sensation / impression

In many contexts, the English translation may still just be feeling, but Hebrew speakers may hear a different tone.

Yes. Without vowel marks (niqqud), הרגש can be ambiguous in writing.

It can represent:

• הָרֶגֶשׁ = the feeling / the emotion
• הַרְגֵּשׁ! = feel! (imperative, singular masculine)

However, in the sentence הרגש חזק, the natural reading is הָרֶגֶשׁ חָזָק = the feeling is strong.

The command reading would usually not fit this sentence naturally.

A simple pronunciation guide is:

ha-RE-gesh kha-ZAK

A few notes:

• הרגש = ha-RE-gesh
• חזק = kha-ZAK

The stress is on:

• RE in הרגש
• ZAK in חזק

The letter ח is pronounced like a throaty kh/ch sound, not like English h.

The root is ר-ג-ש.

This root is connected with emotion, feeling, and being emotionally affected. Some useful related words are:

• רֶגֶשׁ = emotion, feeling
• לְהַרְגִּישׁ = to feel
• הִתְרַגֵּשׁ = to get excited / be moved
• מְרַגֵּשׁ = exciting / moving
• רִגְשִׁי = emotional

Learning roots helps a lot in Hebrew, because it lets you recognize families of related words.

Yes, it is understandable and grammatical, but it can sound a little compact or literary depending on context.

In everyday speech, speakers might also choose other nouns depending on the exact meaning, such as:

• ההרגשה חזקה
• התחושה חזקה

Those can sound a bit more conversational in some situations.

So הרגש חזק is fine, but it may feel slightly more abstract, emotional, or literary than the most casual everyday phrasing.

The basic order is:

subject + description

So:

• הרגש = the subject
• חזק = the description

This is a very common Hebrew sentence pattern in the present tense:

• הילד עייף = the boy is tired
• הבית גדול = the house is big
• הרגש חזק = the feeling is strong

English needs is, but Hebrew normally does not in the present tense.
