הוא דיבר באופן ברור.

• הוא = he
• דיבר = spoke
• באופן = in a manner / in a way
• ברור = clear / clearly in this structure

So the whole sentence means something like He spoke clearly or more literally He spoke in a clear manner.

דיבר is past tense, third person masculine singular.

So:

• הוא דיבר = he spoke
• היא דיברה = she spoke
• הם דיברו = they spoke

The base dictionary form is usually given as לדבר = to speak.

Because the verb לדבר belongs to a pattern in Hebrew where the past tense form is דיבר.

This verb comes from the root ד-ב-ר, connected with speech.
Its past masculine singular form is:

• דיבר = he spoke

This is a very common verb, and the vowel pattern is part of how the verb is built in Hebrew.

באופן literally means in a manner, in a way, or in a fashion.

It is made of:

• ב־ = in / by
• אופן = manner / way

So באופן ברור literally means in a clear manner.

This kind of phrasing is common in Hebrew, especially in slightly more formal or careful speech.

Because ברור agrees with אופן, and אופן is a masculine singular noun.

So:

• אופן ברור = a clear manner
• not אופן ברורה, because that would be feminine and would not match אופן

Even though in English we say clearly, Hebrew often uses a structure like in a clear manner, where the adjective agrees with the noun אופן.

Grammatically, ברור is an adjective meaning clear.

But in this sentence, because it appears in the phrase באופן ברור (in a clear manner), the whole phrase functions like an adverb in English.

So:

• ברור itself = adjective
• באופן ברור = adverbial phrase meaning clearly

It is grammatical and understandable, but it can sound a bit formal or written.

More natural alternatives are often:

• הוא דיבר בבירור = He spoke clearly
• הוא דיבר בצורה ברורה = He spoke in a clear way

So:

• באופן ברור = correct, somewhat formal
• בבירור = very common
• בצורה ברורה = also very natural

Usually, standard Hebrew prefers:

• הוא דיבר בבירור
• הוא דיבר בצורה ברורה
• הוא דיבר באופן ברור

Saying הוא דיבר ברור may be heard in casual speech, but it is generally less standard. For learners, it is safer to use one of the fuller, more accepted forms.

Hebrew does not have an adverb system that works exactly like English -ly.

Instead, Hebrew often expresses adverbial meaning by using:

• a prepositional phrase, like באופן ברור
• another fixed adverb, like בבירור
• a phrase with בצורה, like בצורה ברורה

So where English says clearly, Hebrew often says something more like:

• in a clear way
• with clarity

A simple pronunciation guide is:

Hu diber be'ofen barur.

More roughly for an English speaker:

• הוא = hoo
• דיבר = dee-BER
• באופן = beh-O-fen
• ברור = ba-ROOR

Stress usually falls like this:

• diBER
• beOfen
• baROOR

Yes, it is normal.

The order is:

• הוא = subject
• דיבר = verb
• באופן ברור = adverbial phrase

So the structure is:

He + spoke + clearly

Hebrew often allows some flexibility in word order, but this version is completely natural and straightforward.

Yes. In fact, that is the more literal meaning.

• Literal: He spoke in a clear manner
• Natural English: He spoke clearly

So if you are trying to understand the grammar, the literal version is helpful. If you are translating naturally, He spoke clearly is usually best.
