すいようび

You say 'Wednesday' in Japanese as すいようび (suiyoubi).

すいようび (suiyoubi) means 'Wednesday' in English.

The kanji for すいようび is 水曜日. 水 (sui) means 'water', 曜 (you) means 'day of the week', and 日 (bi) means 'day'.

Sure!
水曜日に映画に行きます。
(Suiyoubi ni eiga ni ikimasu.)
(I will go to the movie on Wednesday.)

It's pronounced sue-ee-yoh-bee. The 'u' sound is like the 'oo' in 'moon', and the 'i' is like the 'ee' in 'see'.

Not really specific phrases, but you'll often see it used with particles like に (ni) to indicate 'on Wednesday', as in 水曜日に (suiyoubi ni).

Like many day names, it comes from the Chinese system based on the five elements. 水 (sui) means 'water', which is associated with Wednesday.

Think of 水 (mizu, water). You could imagine 'water day' for Wednesday. It helps to associate the kanji with its meaning.

すいようび is a standard, neutral word for Wednesday. You can use it in both formal and informal settings.

All the days of the week in Japanese follow a similar pattern: [element/celestial body]曜日. For example, 火曜日 (kayoubi) for Tuesday uses 火 (ka, fire), and 木曜日 (mokuyoubi) for Thursday uses 木 (moku, wood).
