tsp is the short written form of 'teaspoon' or 'teaspoons'. You will almost only meet it in recipes, on food packets, and on the side of medicine bottles — places where space is tight and every line is short. It is written, not spoken: when you read the recipe out loud you say 'teaspoon', never 'tee-ess-pee'.

tsp是'teaspoon'或'teaspoons'的簡寫。 You will almost only meet it in recipes, on food packets, and on the side of medicine bottles你幾乎只會在食譜、食品包裝、藥瓶側面看到它—— places where space is tight and every line is short這些地方空間有限，每一行字都要短。 It is written, not spoken這是寫出來看的，不是唸出來的： when you read the recipe out loud you say 'teaspoon'把食譜唸出來的時候要說'teaspoon'， never 'tee-ess-pee'絕對不會唸成'tee-ess-pee'。

The same form covers one or many, so '1 tsp' and '2 tsp' are both correct and there is no 'tsps'. A full stop after it (tsp.) is fine and common in American books.

The same form covers one or many同一個寫法可以指一個或多個， so '1 tsp' and '2 tsp' are both correct所以'1 tsp'和'2 tsp'都是對的， and there is no 'tsps'而且沒有'tsps'這種寫法。 A full stop after it (tsp.)後面加句點寫成tsp. is fine and common in American books在美式書裡很常見也沒問題。

Keep it apart from tbsp, which is tablespoon — that is three times bigger, and mixing them up will ruin what you are cooking. In recipes the measurement is a proper unit, not really the spoon in your drawer: one teaspoon is about 5 millilitres, so a measuring spoon is more reliable than the one you stir your tea with.

Keep it apart from tbsp要把它跟tbsp分清楚， which is tablespoon tbsp是tablespoon（大匙）—— that is three times bigger大匙是tsp的三倍大， and mixing them up will ruin what you are cooking搞混的話會毀了你在煮的東西。 In recipes the measurement is a proper unit在食譜裡這是一個正式的單位， not really the spoon in your drawer不是真的指你抽屜裡那支湯匙： one teaspoon is about 5 millilitres一茶匙大約是5毫升， so a measuring spoon is more reliable than the one you stir your tea with所以量匙比你平常攪茶用的湯匙準確多了。

In American recipes you will also see it written 't' (small letter) against 'T' for tablespoon, which is a nasty trap.

In American recipes在美式食譜裡 you will also see it written 't' (small letter) against 'T' for tablespoon也會看到用小寫't'對比大寫'T'（代表tablespoon）的寫法， which is a nasty trap這是個很討厭的陷阱。
