How to Pronounce Tech Terms: The Definitive Guide
Cache, nginx, kubectl, daemon, SQL — the 50 most mispronounced tech terms with audio examples and IPA notation.
You have been using these words in code for years. But when you have to say them out loud in a standup, a job interview, or a conference talk — your confidence drops. Here are the most commonly mispronounced tech terms, with the correct pronunciations and the logic behind them.
Why This Matters
Mispronouncing technical terms can undermine your credibility, even if your technical knowledge is solid. More practically, if you say a word differently from everyone else on your team, communication suffers — people may not immediately realise you mean the same thing.
The good news: most of these pronunciations follow a small set of rules once you understand their origins.
The Most Mispronounced Terms
Infrastructure & Systems
| Term | Wrong | Right | Notes |
|---|---|---|---|
| nginx | EN-jinx, EN-gee-ex | EN-jinx (the x = -ks) | Actually /ˈɛndʒɪnks/ — like “engine” + “x” |
| daemon | DAY-mon | DEE-mun | From Greek, rhymes with “lemon” |
| cache | CATCH, CASH-ay | KASH | Rhymes with “cash”. Never two syllables. |
| cron | CRONE, KRAWN | KRON | Rhymes with “on” |
| sudo | SOO-doo | SOO-doh | ”su” = substitute user, “do” = do |
| chmod | CH-mod, CHUH-mod | CH-mod | ”ch” = change, “mod” = mode; say each syllable |
| Linux | LYE-nux, LEE-nux | LIN-uks | Linus Torvalds himself says /ˈlɪnʊks/ |
Web & Networking
| Term | Wrong | Right | Notes |
|---|---|---|---|
| SQL | SEE-kwul, S-Q-L | SEE-kwul or S-Q-L | Both are accepted; “sequel” is most common |
| API | AH-pi | A-P-I | Always spell it out: “ay-pee-eye” |
| OAuth | OH-auth, oh-ATH | OH-auth | ”O” from “Open”, “Auth” = authorisation |
| localhost | LOE-kul-host | LOH-kul-host | ”local” + “host”; stress on first syllable |
| HTTPS | H-T-T-P-S | H-T-T-P-S | Spell it out; never say “hittips” |
| EOF | ee-of | E-O-F | Spell it out: “ee-oh-ef” |
Kubernetes & Cloud
| Term | Wrong | Right | Notes |
|---|---|---|---|
| kubectl | KOO-becktul, KOO-bi-ctl | KYOO-bi-ctl or KOO-ectl | Both used by the community. “cube control” is the most common spoken shorthand |
| Kubernetes | KOO-ber-nee-tees | KYOO-ber-NET-eez | /kjuːbəˈnɛtiːz/ — Greek for “helmsman” |
| AWS | AWZ | A-W-S | Always spell it out |
| GCP | ”Jee-sip” | G-C-P | Spell it out: “jee-see-pee” |
| Terraform | TEAR-a-form | TER-a-form | ”Terra” = Latin for earth |
| etcd | ET-ked, EST-seed | ET-see-dee | Spell it out: “ee-tee-see-dee” |
Languages & Frameworks
| Term | Wrong | Right | Notes |
|---|---|---|---|
| Python | PY-thun | PY-thon | rhymes with “bison” not “button” (British: /ˈpaɪθən/) |
| nginx | — | See above | |
| Vue.js | VYOO, VOO, VEW | VYOO | Rhymes with “view” |
| Next.js | NEXT-jay-es | NEXT | The “.js” is silent in speech |
| Astro | AZ-troh | AS-troh | Short “a” as in “ask” |
| Svelte | SVELT-ee, S-VELT | SVELT | One syllable, rhymes with “felt” |
| Kotlin | KOT-lin | KOT-lin | Short O, two syllables |
| Rust | ROOST | RUST | Short U, rhymes with “must” |
Database & Architecture
| Term | Wrong | Right | Notes |
|---|---|---|---|
| PostgreSQL | POST-gres-quill | POST-gres-Q-L | ”Post-GRES” + spell out “Q-L”: /ˌpoʊstɡrɛs kjuːˈɛl/ |
| Redis | REE-dis | RED-is | Short E, like “red” + “is” |
| Kafka | KAF-kuh, KAY-fka | KAF-kuh | Short A, like the author Franz Kafka |
| gRPC | ”gee-ar-pee-see” | G-R-P-C | Spell it out |
| YAML | YAAH-mul | YAA-mul | Two syllables: “YAM-ul” |
| JSON | JAY-son or J-S-O-N | JAY-son | Like the name Jason — this is correct |
Three Rules That Cover Most Cases
Rule 1: Acronyms are almost always spelled out
API, SQL, HTTP, DNS, VPN, JWT, CSS, REST, SOAP — say each letter individually unless the industry standard is a word (e.g. “sequel” for SQL is widely accepted).
Rule 2: Open-source project names follow their creator’s pronunciation
When in doubt, watch a conference talk by the project’s creator. Linus says “Linux”, Guido says “Python”, Evan You says “Vue” (like “view”).
Rule 3: Silent letters in English
Many English words have silent letters that trip up non-native speakers:
- “cache” — the
-cheis not pronounced - “colonel” — pronounced “kernel” (relevant: Linux kernel)
- “mnemonic” — the M is silent: /nɪˈmɒnɪk/
Building Confidence
The single best exercise: watch conference talks. When you hear a speaker say “Kubernetes” or “Terraform” naturally, in context, your brain maps the pronunciation to the concept you already have. PyCon, KubeCon, JSConf, and re:Invent talks are all on YouTube and free.
Say terms out loud when you use them. This sounds obvious, but many developers silently read and write tech terms for years without ever vocalising them. Speaking them — even to yourself — builds the muscle memory for when you need them in a meeting.
