Reductions in fast speech
Reductions are whole phrases collapsing into a single fast syllable: going to becomes gonna, want to becomes wanna, should have becomes shoulda, kind of becomes kinda, out of becomes outta, and what's up becomes 'sup. They are the standard pronunciation of these phrases at natural speed in every accent, not slang — but they are sounds, not writing, and the full forms return whenever the word or phrase is stressed.
The words that dissolve in fast speech
English speakers do not always pronounce the words they intend. going to comes out gonna, should have comes out shoulda, and what's up comes out 'sup. These are reductions — whole phrases collapsing into a single fast syllable because the mouth, at natural speed, takes the shortest route between the stressed sounds. They are not slang in the sense of being new words; they are old words worn smooth by use.
The critical thing to understand is that reductions are sounds, not writing. Gonna in a text message is a deliberate casual spelling; in speech, /ˈɡʌnə/ is what almost everyone says almost every time, in every register, including news read slow enough to understand. Treat these spellings as pronunciation guides and never as words to write in formal prose — except where they have genuinely entered casual writing, like 'sup.
Gonna, wanna, gotta — the famous three
Predicting where reductions happen is easy: they appear wherever a function word — to, have, of — is unstressed, which is almost always. going to reduces the "to" to /ə/ and then the two words fuse into /ˈɡʌnə/. want to does the same and absorbs the /t/ entirely, giving /ˈwɒnə/ with no trace of the t at all — the spelling wanna is phonetic in a way the full form is not. (have) got to becomes /ˈɡɒtə/.
Because they are so frequent, these three are the highest-value reductions a learner can acquire. They work in both directions: hearing /ˈɡʌnə/ and knowing it is "going to" unlocks whole conversations, and producing it is the single quickest way to stop sounding like a textbook. The alternative — saying /ɡoʊɪŋ tuː/ at full value — is not wrong, but it is the pronunciation of someone reading aloud, and natives will unconsciously hear it as emphasis.
Shoulda, coulda, woulda — have as a ghost
The perfect forms — should have, could have, would have — reduce by erasing the word "have" almost completely. Its /h/ disappears and its vowel collapses to /ə/, leaving only a light /v/ or nothing at all: /ˈʃʊdə/, /ˈkʊdə/, /ˈwʊdə/. Native speakers write "should've" when they are being careful and "shoulda" when they are transcribing speech, and the pronunciation is the same either way — which is, again, why the misspelling "should of" is so common.
These reductions are optional in a way gonna is not — /ʃʊd hæv/ at full value is acceptable careful English — but they are the norm at any speed above deliberate dictation. They also stack with modals you might not expect: must've (/ˈmʌstə/), might've (/ˈmaɪtə/), could've been. Once you hear the pattern, the whole family is one sound shape: modal + /ə/.
Kinda, outta, cuppa — of and up disappearing
The word of is a reduction machine: unstressed in almost every phrase, it collapses to /ə/ and fuses with the word before it. kind of becomes /ˈkaɪndə/, sort of /ˈsɔːtə/, a lot of /əˈlɒtə/ — the schwa of "of" even merges with the "a". cup of is so reduced it has its own spelling, cuppa. And out of becomes /ˈaʊtə/, giving the immortal get outta here.
'sup shows the same process at phrase level. What's up loses the /w/ and the first vowel — what's left is /sʌp/, a single syllable that still means the full greeting. Reductions this aggressive are the greeting register, not the sentence register: they belong with friends, not in a job interview, but you will hear them constantly and should recognise them instantly.
Dunno, gimme, lemme — the casual set
A final group packs elision and assimilation together. don't know drops the /t/ (as all don't forms do before consonants) and merges into /dəˈnoʊ/ — dunno. give me and let me weaken their second syllables to /ɪ/ and fuse: /ˈɡɪmi/, /ˈlɛmi/. And do you at the start of questions is so compressed that it is usually /dʒə/ — the assimilation of t/d + y at full throttle.
The line between "reduction everyone uses" and "reduction that sounds sloppy" is real but blurry. Gonna, wanna, gotta, shoulda, kinda and outta pass almost anywhere casual. Dunno and gimme signal relaxed, informal speech — fine with friends, wrong in a presentation. Let context be your guide and never, ever write them in formal work; in speech, match the room.
How to practise reductions
The listening skill comes first: take a podcast or film and hunt for the reduced forms — you will find them in nearly every sentence. Then produce them with the conversion drill: read a sentence aloud in full form, then again converted, then at natural speed. I am going to go to the store / I'm gonna go to the store. The converted version should take less time and should feel lighter, because that is exactly what reductions are for — fitting more meaning into the same stress-timed beat.
Finally, shadow a few minutes of dialogue daily with shadowing, consciously copying the reductions the speaker makes. Within a week or two your mouth will reach for /ˈɡʌnə/ and /ʃʊdə/ automatically — and you will finally understand why native speech had been outpacing you: it was not faster, it was more reduced.
FAQ
Is it bad English to say gonna or wanna?
No. They are the standard pronunciation of going to and want to in casual and semi-formal speech. What is bad is writing them in formal text, or saying them in very formal speech where the full form is expected. Match the register and they are entirely correct.
Will using reductions hurt my exam score?
In speaking tests, natural reductions help — IELTS and TOEFL reward natural rhythm and connected speech. In formal writing, use full forms. The skill is using the right register, not avoiding reductions.
What is the difference between shouldn't and shoulda?
Both are reductions of different things. Shouldn't = should not, an n't contraction. Shoulda = should have, a perfect-form reduction. They are often confused because "shouldn't have" reduces to /ˈʃʊd.ən.ə/ — shouldna — which sounds close to shoulda but is not the same.
Do all English accents reduce the same way?
Yes, in the same patterns — gonna, wanna and shoulda occur in American, British, Australian and most other native varieties. Vowel quality differs slightly (gonna /ˈɡʌnə/ vs /ˈɡɒnə/), but the reductions themselves are universal.
How do I know when NOT to reduce?
Never reduce a word that carries stress: "I'm going to GO", "WHAT'S up?", or a sentence-final to: "That's what I'm going TO." Reduced words are never contrastive, never final, and never emphasised — stress is the signal that the full form must appear.

Quick pronunciation tips
Read slowly first. Pronounce each syllable deliberately before trying to blend them at full speed. Rushing hides the vowel and consonant shapes your ear needs to learn.
Record yourself. Most phones have a voice memo app — record a word, then compare it to the playback here. Hearing the gap between your version and the model accent makes targeted practice far easier.
Focus on one accent. Jumping between American, British and Australian in the same session creates confusion. Pick the accent you encounter most and stick with it until the patterns feel natural.
