You are three slides into a project update. The bullet on the screen reads: Ship the beta to internal teams (e.g., support, sales) by Friday, i.e., before the code freeze. You read it out loud exactly as it is written, letter by letter, and the room goes slightly flat. Someone asks you to repeat the second half.
Your grammar was fine. Your vowels were fine. The problem is that you read a writing convention as if it were speech. English text is full of shortcuts that medieval scribes invented to save ink, and almost none of them are meant to leave your mouth in the shape they appear on the page.
The rule
In spoken American English, most Latin abbreviations are read as their English meaning, not as letters and not as Latin.
You see e.g. and you say for example. You see i.e. and you say that is. You see cf. and you say compare. Four characters on the page become two ordinary English words in the air. The written form is a scribal shortcut; speech has its own version, and the two were never required to match.
A short list of abbreviations breaks this rule, and an even shorter list keeps its Latin intact. Both lists are below and both are small enough to memorize in an afternoon. But if you apply only the default, you will already sound natural nearly every time.
Why the written and the spoken forms drifted apart
Medieval copyists wrote by hand on expensive parchment. Exempli gratia shrank to e.g., id est to i.e., et cetera to etc., nota bene to N.B. The abbreviation existed to save space, not to be pronounced. A reader of the period saw the mark and spoke the full Latin phrase.
English borrowed the marks but not the Latin habit. When a modern American reader hits e.g. mid-sentence, the eye recognizes the shape and the inner voice supplies for example with no conscious translation step at all. That is why saying the letters out loud feels like a stumble to the listener: you have handed them the ink-saving device instead of the message.
This also explains something learners find strange. Nobody is going to correct you for saying ee-jee, because it is not wrong. It is simply the reading voice, not the speaking voice, and the gap between those two registers is exactly what makes a speaker sound at home in the language.
Category one: say the English meaning
These are the ones where the letters almost never leave your mouth in casual or professional speech.
- e.g. becomes for example /fɚ ɪɡˈzæmpəl/. Spelling it as ee-jee /ˌi ˈdʒi/ does happen, but it sounds bookish outside academic settings.
- i.e. becomes that is /ˈðæt ɪz/ or in other words /ɪn ˈʌðɚ ˌwɝdz/. It is never ee-eye; the letter order is I then E, and reversing it is a common learner slip.
- viz. becomes namely /ˈneɪmli/. Almost nobody says the letters.
- cf. becomes compare /kəmˈpɛr/ or see /si/.
- N.B. becomes note that /ˈnoʊt ðæt/ or please note /pliz ˈnoʊt/.
- c. or ca. becomes around /əˈraʊnd/ or about /əˈbaʊt/. A date written c. 1650 is spoken as around sixteen fifty.
Notice what they have in common: each one stands for a full phrase, and each phrase has a plain English equivalent that fits smoothly into a sentence. Speech prefers the phrase.
Category two: say the letters
A handful of abbreviations went the other way and became genuine letter names in speech. Nobody expands these.
- a.m. /ˌeɪ ˈɛm/ and p.m. /ˌpi ˈɛm/, always, with the stress on the second letter. Saying ante meridiem in a meeting would be theatrical.
- P.S. /ˌpi ˈɛs/ at the end of a message.
- AD /ˌeɪ ˈdi/ and BC /ˌbi ˈsi/ for years. BC is always letters; AD is always letters too, even though it stands for a Latin phrase.
- a.k.a. /ˌeɪ keɪ ˈeɪ/, three letter names in a row, stress on the last.
These share a different property: they attach to numbers or names rather than to clauses, so there is no natural phrase to slot in. Nine ante meridiem has no rhythm. Nine a.m. does.
Category three: say it as an English word
A few abbreviations kept their Latin, but the Latin has been fully anglicized, so you are really pronouncing an English word now.
- etc. is spoken in full as et cetera /ɛt ˈsɛtərə/. You never say the letters, and you never say and etc., because the et already means and.
- et al. is /ɛt ˈæl/ or /ɛt ˈɑl/, very common in academic speech when citing multi-author work.
- vs. is versus /ˈvɝsəs/. In legal citation the written v. is often read simply as v /vi/, as in Brown v Board.
The full list

|---|---|---|---|---|
| e.g. | exempli gratia | for example | /fɚ ɪɡˈzæmpəl/ | Safe everywhere; letters only in academic talk |
| i.e. | id est | that is / in other words | /ˈðæt ɪz/ | Safe everywhere; letters risk being misheard |
| viz. | videlicet | namely | /ˈneɪmli/ | Written form is formal; spoken form is neutral |
| cf. | confer | compare / see | /kəmˈpɛr/ | Academic writing; say the English aloud |
| N.B. | nota bene | note that | /ˈnoʊt ðæt/ | Stiff if spelled out in speech |
| c. / ca. | circa | around / about | /əˈraʊnd/ | Neutral; circa itself sounds formal |
| etc. | et cetera | et cetera | /ɛt ˈsɛtərə/ | Neutral in every register |
| et al. | et alii | et al | /ɛt ˈæl/ | Academic and professional speech |
| vs. / v. | versus | versus (legal: v) | /ˈvɝsəs/ | Neutral; v only in case names |
| a.k.a. | also known as | ay kay ay | /ˌeɪ keɪ ˈeɪ/ | Informal to neutral |

| AD / BC | anno Domini / before Christ | ay dee / bee see | /ˌeɪ ˈdi/, /ˌbi ˈsi/ | Always letters |
Four traps worth drilling
1. It is et cetera, not excetera
The most frequent error in the whole set. Learners produce eck-cetera or excetera, inserting a /k/ that is not there. There is no letter x in the word. The consonant cluster in the middle is /t s/: your tongue tip closes for /t/ and then releases straight into the hiss of /s/, with no back-of-the-tongue closure at any point. The first syllable is /ɛt/ with the vowel of bet, not the vowel of eat. Say it in three beats first, /ɛt ˈsɛ tə rə/, then let the last two collapse into a fast /tərə/. Many speakers reduce further to /ɛt ˈsɛtrə/, which is perfectly standard.
2. a.m. and p.m. put the stress on the second letter
Both are /ˌeɪ ˈɛm/ and /ˌpi ˈɛm/, with the main beat on the M. Flat, evenly stressed letters sound robotic. They also link tightly to the number before them: nine a.m. is /naɪn eɪ ˈɛm/, said as one rhythmic unit with no pause before the letters. Practice it as if it were a single three-syllable word.
3. versus has two different vowels and two /s/ sounds
It is /ˈvɝsəs/. The stressed first syllable takes the r-colored vowel of her, and the unstressed second syllable takes a plain schwa, so the two vowels are not the same. Both letter s sounds are /s/, never /z/, which keeps it distinct from verses /ˈvɝsəz/. Stress lands firmly on the first syllable.
4. i.e. and e.g. sound almost identical as letters
Say ee-eye and ee-jee across a conference line and a listener has to guess which one you meant, and they mean opposite things: e.g. introduces a partial example, i.e. introduces a complete restatement. Getting that wrong changes the content of the sentence. This ambiguity is the single strongest practical argument for saying the English meaning out loud, and it is why for example and that is dominate real speech.
Exceptions and complications
Academic and legal speech does spell them out
In a seminar, a law lecture, or a lab meeting, you will hear ee-jee and ee-eye spoken as letters quite freely. This is a field convention, not an error. If the people around you say the letters, say the letters. Outside those rooms, default back to the English phrase.
Ending a list on etc.
Speakers often trail off after et cetera, letting the pitch drift and the sentence dissolve. The fix is intonation: give et cetera a clear falling tone and stop. Better still, end the list cleanly with and so on, and things like that, or simply by naming the last item and stopping. A list that ends decisively sounds far more confident than one that fades.
Reading from a slide versus speaking freely
When you read a slide aloud, you are performing written text, and the temptation is to voice every character on it. Do the opposite. Let your eye take in the abbreviation and let your mouth produce the spoken equivalent. Audiences follow the meaning, and they already see the letters.
The a.m. and p.m. habit itself
If you grew up on a 24-hour clock, the twelve-hour system is a second layer of work on top of the pronunciation. Fourteen thirty has to become two thirty p.m. before you can say it. Practice the conversion separately from the sounds, or you will hesitate mid-sentence and the stress pattern will collapse.
The drill: five steps out loud
- Say et cetera ten times slowly, /ɛt ˈsɛtərə/, checking that no /k/ appears. Then say it inside a list: Bring a pen, a notebook, et cetera. with a firm falling tone on the last syllable.
- Say the clock pairs with second-letter stress: nine a.m., six p.m., eleven a.m., each as one linked unit, /naɪn eɪ ˈɛm/.
- Take this written sentence and speak it: Several teams (e.g., support) miss the deadline, i.e., they file late. Say for example and that is. Do not say a single letter.
- Contrast the pair aloud: versus /ˈvɝsəs/ then verses /ˈvɝsəz/, five times. The difference is the final consonant only.
- Record yourself reading a paragraph of your own writing that contains at least three abbreviations. Play it back and mark every place you voiced a letter. Reread it, replacing each one with its English phrase, and compare how much easier the second version is to follow.
The abbreviation is for the page, and the phrase is for the room. Once that split is automatic, take these forms into connected speech with word-level pronunciation practice and then put them inside full sentences with sentence practice.
