takkyuu wo suru.

It is read たっきゅう (takkyuu).

A couple of pronunciation points:

• っ is a small tsu that creates a brief pause or doubled consonant: た・っ・きゅう
• きゅう sounds like kyuu

So it sounds roughly like tak-kyoo, with a little stop before the k sound.

Here, 卓球 is a noun meaning table tennis.

It is not acting like a verb by itself. The verb action comes from する, so the whole pattern is:

• 卓球 = table tennis
• を = marks it as the thing being done
• する = to do

So literally, the sentence is something like do table tennis.

を marks the direct object of the verb.

In 卓球をする, the thing being done is 卓球, so を shows that relation.

This is a very common pattern in Japanese:

• サッカーをする = play soccer
• テニスをする = play tennis
• 勉強をする = do studying / study

So in this sentence, 卓球 is the activity, and する is the verb to do.

Japanese often expresses activities by using a noun + する pattern instead of having a separate verb like English does.

English says:

• play table tennis

Japanese says:

• 卓球をする
• literally: do table tennis

This is completely normal Japanese. English uses different verbs like play, do, or study, but Japanese often uses する for many kinds of actions and activities.

In natural English, you would usually translate it as play table tennis.

Even though する literally means to do, translations should sound natural in English. So for sports, play is usually the best translation.

Literal structure:

• 卓球をする = do table tennis

Natural English:

• play table tennis

Japanese often omits the subject when it is obvious from context.

So 卓球をする。 could mean:

• I play table tennis.
• He plays table tennis.
• We will play table tennis.
• (Someone) plays table tennis.

The exact subject depends on the situation. Japanese frequently leaves out words that English usually requires.

By itself, する in plain form can refer to:

• a habitual action: (I) play table tennis
• a future action: (I) will play table tennis
• a more general statement: (someone) plays table tennis

Japanese non-past forms often cover both present and future. Context tells you which meaning is intended.

卓球をする。 is in the plain form, so it is less formal / casual.

The polite version is:

• 卓球をします。

So:

• 卓球をする。 = plain
• 卓球をします。 = polite

You would usually use します in polite conversation, with teachers, coworkers, customers, and so on.

For a learner, the safest and most standard form is:

• 卓球をする

You may sometimes encounter noun + する without を in Japanese, but with sports and many ordinary activity nouns, を is the basic pattern you should learn first.

So if you want to say play table tennis, use:

• 卓球をする

The order is:

• 卓球 = object/activity noun
• を = object marker
• する = verb

Japanese usually puts the verb at the end of the sentence.

So this follows a very common Japanese pattern:

• [object] を [verb]

Examples:

• 本を読む = read a book
• 音楽を聞く = listen to music
• 卓球をする = play table tennis

In this sentence, 卓球 means the sport/activity of table tennis.

If you want to refer to the paddle, ball, or table, Japanese would normally use other words depending on what exactly you mean.

So in 卓球をする, 卓球 clearly refers to the activity itself.

You can add a topic or subject if you want:

• 私は卓球をする。 = As for me, I play table tennis.
• 僕は卓球をする。 = I play table tennis. (common for males)
• 俺は卓球をする。 = I play table tennis. (more casual/rough)

In polite form:

• 私は卓球をします。

But in many real conversations, Japanese would simply say:

• 卓球をする
• 卓球をします

because the subject is understood from context.

A natural polite question is:

• 卓球をしますか。

A casual version is:

• 卓球をする？

If you want to include you, Japanese often still leaves it out unless needed. So you usually do not need to say あなたは.
