One syllable: inf.
/ˈɪnf/
Say it backInf is an informal abbreviation for information, often used in digital communication. In specialist contexts it can also function as shorthand in mathematics or computer science to denote an infinitesimal or infinite limit, though usage varies by field. The term is typically pronounced as a short, clipped word in casual speech and rarely stressed heavily in longer phrases.
"I found some inf on the topic in that article."
"Send me the inf for the dataset before we proceed."
"He tapped the shortcut and opened the inf window."
Pronounce it as a single syllable with the short vowel /ɪ/ followed by /n/ and /f/, like “inf” in information. The stress is typically light; the word is clipped and fast in natural speech. IPA: US/UK/AU /ɪnf/. In connected speech, the final /f/ can be subtly devoiced. Consider saying “ih‑nf” with the tongue touching the alveolar ridge for /n/ and a crisp labiodental /f/ release.
Common mistakes include saying a longer vowel, treating it like two syllables, or misarticulating the final /f/ as /v/. To correct: keep a short, lax /ɪ/; end with a clear, unvoiced /f/ by gently touching the bottom lip to the upper teeth and forcing air through the small gap. Keep the tongue neutral and avoid adding a vowel after the /f/. Practice with a quick envelope: /ɪn͡f/ without extra sound.
Across US/UK/AU, /ɪnf/ remains the same vowel quality, but tempo and voicing of /f/ can vary. US speakers may be slightly quicker with lighter alveolar nasal /n/, UK speakers can show crisper /f/ with more precise lip seal, and AU speakers often carry a slightly more open quality on the vowel due to broader accent features, but the core /ɪnf/ remains consistent. Do not add a rhotic or extra vowel in any of these varieties.
The challenge is achieving a clean, unvoiced /f/ at the end and maintaining a short /ɪ/ in a rapid sequence. In connected speech you may get vowel reduction or a lengthened /ɪ/ before a consonant cluster; keep the jaw relaxed and the tongue neutral to prevent an unintended vowel after /n/. Also avoid letting the /n/ blend into a nasalized or rounded vowel.
In technical contexts, some readers may encounter 'inf' as shorthand within code or notes; you should still pronounce it as /ɪnf/ when reading aloud or telling someone the term. Even when embedded in strings like “inf data,” maintain the same clip and avoid emphasis. The unique aspect is its status as an abbreviation; in formal reading, spell it out, but in casual talk, keep the brief, crisp /ɪnf/ sound.

Inf, short for information or infinitesimal in mathematical notation, originates in mid-20th-century English as a clipped form widely adopted in computing, engineering, and everyday digital shorthand. The abbreviation likely derives from the practice of creating brevity in technical discussions, where long terms are routinely shortened (e.g., info, info‑sec). The sense of information became dominant in general usage from the 1960s onward, paralleling the rise of information technology and online communication. In mathematics and physics, inf is used in notations like infinitesimal (dx, dy) or infinite limits (lim x→∞), but when abbreviated, “inf” is often used in notes or software comments to avoid clutter. First known uses appear in technical memoirs and early computer manuals where glossary terms were abbreviated to keep code and notes concise. Over decades, inf has become a conventional, widely understood symbol in casual speech, though formal writing tends to spell out “information” or use the proper mathematical notation rather than the abbreviation. Today, inf appears across chat slang, documentation, and code comments, preserving its short, utilitarian character across disciplines.
