Sana dumalo ang lahat sa okasyon.

Sana expresses a wish, hope, or desired situation. In English, it often corresponds to I hope, hopefully, or sometimes if only, depending on context.

In Sana dumalo ang lahat sa okasyon, it shows that the speaker wants everyone to attend the occasion.

That is a very normal Tagalog word order. Tagalog often puts the predicate first, and the ang-marked topic comes after it.

So the structure is roughly:

Sana + dumalo + ang lahat + sa okasyon

This is different from English, which usually prefers subject + verb order. In Tagalog, verb-first or predicate-first order is common and natural.

Not in meaning, even though it can look like a completed form.

Dumalo comes from an -um- verb, and this form can function in ways that do not always map neatly onto English tense. After sana, Tagalog very often uses this form to express a hoped-for action, even if it refers to the future.

So here, dumalo means something like:

• attend
• would attend
• will attend

depending on how you translate it into English.

Dumalo comes from the root dalo, which is related to attending or visiting.

It is formed with the infix -um-:

dalo → d-um-alo → dumalo

This makes it an actor-focus verb. That means the doer of the action is marked by ang, which is why we get ang lahat as the group doing the attending.

Ang marks the topic or subject-like part of the sentence.

Lahat means all or everyone, and here it stands by itself as a noun-like expression. So ang lahat means:

• everyone
• all of them
• all the people concerned

It usually refers to a group already understood from context, such as all the guests, all the members, or all the invitees.

Usually no. In real usage, lahat normally means everyone in the relevant group, not every person on earth.

So in this sentence, ang lahat most likely means everyone involved or everyone expected, such as all the invited people.

Sa is a very common marker that often corresponds to English in, at, to, or for, depending on context.

Here, sa okasyon means something like:

• at the occasion
• at the event
• for the occasion

So sa introduces the place or event connected with the action of attending.

Yes. Okasyon is a normal and understandable word, especially in somewhat formal or general contexts. It means occasion or event.

Depending on the situation, speakers might also use other words such as:

• pagtitipon for a gathering
• pagdiriwang for a celebration
• event in casual modern speech

But okasyon works well in this sentence.

Yes. Some natural alternatives are:

• Sana lahat ay dumalo sa okasyon.
• Sana ay dumalo ang lahat sa okasyon.

These are very close in meaning. The differences are mostly in style, rhythm, or emphasis, not in the core message.

Tagalog often leaves that unstated. The speaker's wish is already understood from sana, so there is no need to add a separate word for I.

That is why sana by itself can often carry the sense of I hope in English, even though no pronoun appears in the Tagalog sentence.
