IT Acronyms: Say As Word or Spell Out?
NASA, SCRUM, ASCII, RAM — said as words. SQL, HTTP, URL, API — spelled out letter by letter. Learn the rule and practise with 20 common IT acronyms.
The rule at a glance
- Say as a word (acronym) — letters form pronounceable syllables: RAM = "ram," SCRUM = "skrum," ASCII = "ASS-key," CRUD = "crud," REST = "rest," YAML = "yam-el," BIOS = "BY-oss"
- Spell out (initialism) — consonant clusters that resist syllables: HTTP = "aitch-tee-tee-pee," API = "ay-pee-eye," URL = "you-ar-el," SQL* = "ess-cue-el," CSS = "see-ess-ess," IDE = "eye-dee-ee"
- Edge cases: SQL is debated — "sequel" vs "ess-cue-el" (both accepted); GIF is debated — "jif" vs "gif"
- Quick test: try saying the letters as a single word. If it sounds natural, say it as a word. If it feels forced, spell it out.

Question 0 of 5
How do most developers pronounce NASA when using it as a comparison (e.g. "NASA-scale infrastructure")?
"NAY-suh" is correct. NASA is a classic acronym — it has pronounceable syllables and is always said as a word. Developers borrow it in phrases like "this is not NASA" or "NASA-level reliability." No one spells it out as "en-ay-ess-ay." The same logic applies to IT acronyms: if the letters form natural syllables, say it as a word.
How is ASCII pronounced?
"ASS-key" is the standard pronunciation — two syllables, stress on the first. It stands for American Standard Code for Information Interchange. The double-I at the end is silent in spoken use; the name was designed to be pronounceable. You will hear "ASCII art," "ASCII character," "ASCII table" all said "ASS-key" universally.
A colleague says "I'll hit the API endpoint." How do they pronounce "API"?
"AY-pee-eye" is correct — API is an initialism, not an acronym. The three letters A, P, I do not form a natural syllable cluster in English, so developers always spell them out. You will always hear "ay-pee-eye endpoint," never "app-ee endpoint." Compare: REST is a word ("rest"), but API is three distinct letter sounds.
How is SCRUM (the Agile framework) pronounced?
"Skrum" — exactly like the rugby term it was borrowed from. SCRUM is always pronounced as a single word; no developer ever spells it out as "ess-see-ar-you-em." In fact, Scrum is now so commonly written in mixed case ("Scrum," not "SCRUM") that many people forget it started as an abbreviation at all. Saying "skrum master" and "skrum team" is universal.
How do most developers say HTTP?
"Aitch-tee-tee-pee" is standard in British English. HTTP is an initialism — the consonant cluster HTTP cannot form a natural English syllable, so each letter is said separately. Note: in British English the letter H is "aitch" (not "haitch"); "haitch" is considered non-standard in formal settings. You will hear "aitch-tee-tee-pee-ess" for HTTPS.
