I have written many emails introducing vocabulary words from The New York Times’ “Word of the Day” articles for English learners.
Today, I happened to think of a word to share with you myself—“caveat,” a noun meaning a “warning” or “condition” attached to something being stated. It is often used when the terms and conditions of something, such as an agreement or policy, are being laid out. For example:
The agreement is subject to one caveat: either party may terminate it with 30 days’ notice.
這項協議附帶一項限制條件：任何一方均可提前三十日通知終止協議。
The offer comes with one important caveat, which is that it is only available to existing customers.
這項優惠附帶一個重要條件：只適用於現有客戶。
This word came up as an example when I was explaining to a student enrolled in our vocabulary course that the English spelling system is famously opaque—that is, there is no truly consistent correspondence between the letters and letter strings we use to spell English words and the actual phonemes (individual consonant and vowel sounds) they represent.
There are many historical reasons for this. One major reason is that English has borrowed many words from other related languages that also use Roman letters in their writing systems, while retaining the ways in which those loanwords were originally written.
As such, even after these loanwords have evolved in English to become full-fledged English words with English phonological characteristics, their spellings still reflect their “original” written forms, which captured their pronunciation in their languages of origin.
“Caveat” is a Latinate loanword that has now evolved into a common English word. It is pronounced /ˈkæ vi ɑt/ (three syllables, with these vowel phonemes). As you can see, its spelling still reflects the word’s Latinate etymological origins.
If you simply looked at this English word without already knowing how it is pronounced, you would naturally draw the wrong conclusions about its pronunciation based on certain English “spelling conventions” you know.
In particular, you would probably assume that it is a two-syllable word, with “-veat” representing one syllable, likely with the vowel /i/ (as in “heat” and “beat”). “-veat” in this word actually represents two syllables: /vi ɑt/.
This is why it is important to have a conscious understanding that English spelling is opaque. Even though there are certain spelling conventions that allow us to “predict” how a previously unknown word is pronounced, the “system”—to the extent that there is one—is actually highly inconsistent, especially when we get to “higher level” words that have different etymological origins.
You should always look up how a new English word is pronounced to be certain. Otherwise, you might find yourself in some embarrassing situations—imagine trying to use the word “caveat” in a professional context and pronouncing it with the wrong vowels!
This is where knowledge of English phonemes and the IPA’s one-to-one system of representation comes in handy!
我之前寫過不少電郵，介紹《紐約時報》為英語學習者而設的「每日一字」（Word of the Day）文章中的詞彙。
今天，我自己剛好想到一個字想跟大家分享——caveat。這是一個名詞，意思是「警告」或「附帶條件」。當我們列出協議或政策的內容時，就經常會用到這個字，去預先提醒對方條件是甚麼。例如：
The agreement is subject to one caveat: either party may terminate it with 30 days’ notice.
這項協議附帶一項限制條件：任何一方均可提前三十日通知終止協議。
The offer comes with one important caveat, which is that it is only available to existing customers.

我剛向一位正在修讀我們詞彙課程的學生解釋，英文的 spelling 系統是出了名地 opaque （不透明）的，用了這個字作例子。
所謂「不透明」，就是我們用來拼寫英文詞語的字母及字母串，跟它們實際代表的 phonemes（音素，即英文個別的子音和母音）之間，並沒有真正完全一致的對應關係。
造成這個現象的歷史原因有很多。其中一個主要原因，就是英文在演變中從其他有「親戚關係」的語言借了大量詞語。這些語言同樣使用羅馬字母作為書寫系統，而英文在借入這些詞語時，往往保留了它們原本的拼寫方式。
因此，即使這些外來字進入英文之後，至今已經演變成具有英文語音特徵、完完全全的英文字，它們的拼寫仍然會反映其「原本」的書寫形式——也就是原先用來記錄它們在來源語言中讀音的形式。
Caveat 是拉丁文借字，如今已經演變成一個常見的英文字。它讀作 /ˈkæ vi ɑt/，共有三個音節，當中包含這幾個母音音素。大家可以看到，它的拼寫仍然反映了這個字的拉丁文字源。
如果你事前不知道這個英文字的讀音，只看它的拼寫，便很自然會根據你所認識的某些英文「拼寫規律」，對它的讀音作出錯誤推斷。
例如，你很可能會以為它是一個兩個音節的字，並把 -veat 這部分視為一個音節，當中的母音很可能是 /i/，就像 heat 和 beat 中一樣。但事實上，這字中的 -veat 代表的是兩個音節：/vi ɑt/。
這正正說明了為甚麼我們必須清楚意識到，英文的拼寫系統並不透明。雖然英文的確有某些拼寫「規律」，讓我們可以「預測」一個從未見過的字應該怎樣讀，但這套「系統」其實非常不一致，尤其是當我們接觸到有很多不同字源的「高階」詞彙時。
因此，每當你學到一個新的英文字，都應該主動查清楚它的讀音，以確保自己讀得正確。否則，你可能會遇到一些尷尬的情況——試想像一下，你在工作場合中嘗試使用 caveat 這個字，卻用了錯誤的母音去讀它！
這正是認識英文音素，以及國際音標（IPA）這套一對一標音系統有用的地方。
