How do you pronounce “with something”?

I concur with the commenter who said to practice saying "months" to help with the transition. I'll also add that depending on the accent and whether you're in a professional setting it does get fully pronounced, I at least typically don't drop the "th" at the end of "with" but I *do* make it glide quickly into the "s" of "something"

ths That’s tricky. I’d practice just that sound th-ss

Try "withezompthing"

It sounds like you may have gotten it, but if you make the th sound and pull your tongue backwards but change nothing else, you’ll make the s. I close my teeth a bit more then, when I make the s, but that’s the main motion: pulling your tongue out from between your teeth.

I think I say “wihsomething”

Don't force yourself to say them faster. Practice slower, and the muscle memory can get quicker over time.

Depends on my mood. Scottish - Wi' some'hing Essex - Wiv sumfink SSB - with something Estuary - Wiv summin Caribbean - wit sumting

In Scotland (and I think loads of other places) it'll get slurred to wi'some'ing. English is a stress-timed language and it's ok to slur over the unstressed ot less important syllables. \[Caveat: I am not a teacher\] Check out Rachel [https://youtu.be/PrAe07KluZY?si=ThNumgLP540IVAEn](https://youtu.be/PrAe07KluZY?si=ThNumgLP540IVAEn)

*wi'thsssss - umthing*

I just listened to myself closely when I say "with something" and there is a very very slight lisp in the transition between the sounds. I doubt anyone would ever hear it. My accent is British English (roughly RP), and that probably makes it easier, because the th is with is always voiced in my accent. If you're saying "with" unvoiced, that might make it harder, but it will still normally be hard for others to hear.

I'm not sure what language you're coming from, but it is a common theme across all the ones I'm familiar with: if the first word ends with a sound that is similar to the start of the next word, you drop one of them. Unless I was speaking slowly and deliberately, I would probably say "wissomething" I don't speak much Portuguese, but I've heard the phrase "seu aviao" and it ends up sounding more like "syaviao" to my ears

“wi sump’m”

Practice saying 'months', we make a smooth transition from a reduced th sound into an s sound, so start with a th sound but quickly pull your tongue back in behind your teeth to s sound.
