Con Junction
Concede a point, contrast two things, rule out both — smoothly, out loud.
Aunque + indicative concedes a fact you know is true: aunque llueve, vamos a salir. After a negation, a correction takes sino, not pero: no es alemán, sino austriaco — pero is for plain contrast (es caro, pero vale la pena). Mientras alone means while, two things at once (escucho música mientras cocino); mientras que means whereas, a contrast (yo prefiero el té, mientras que ella prefiere el café). And ni…ni is neither…nor — keep the no when the verb comes first: no tengo ni tiempo ni dinero.
Below: the sentences each connector carries, the pero-for-sino slip that marks a learner, and a way to practise them out loud in a real back-and-forth — no drills, no fill-in-the-blanks.
The warm-up pack
Aunque, sino, mientras — the small connectors that make a sentence sound native instead of translated word for word.
01 · Even though, and doing it anyway
Aunque llueve, vamos a salir.
Even though it's raining, we're going out.
Aunque pairs with a plain present tense here because it's raining is a known fact, not a maybe — you're conceding it and moving on.
02 · The correction, not the contrast
No es alemán, sino austriaco.
He's not German, but Austrian.
Sino only shows up after a no — it swaps one fact for the correct one. It's not for general contrast, that's pero's job.
03 · When pero is the wrong word
No quiero té, sino café.
I don't want tea, but coffee.
Try pero here and it reads oddly to a native ear — the sentence is correcting what you want, not just adding a contrast, so it needs sino.
04 · At the same time
Escucho música mientras cocino.
I listen to music while I cook.
Mientras on its own just means "while" — two things happening at once. No que needed.
05 · Whereas — the extra que
Yo prefiero el té, mientras que ella prefiere el café.
I prefer tea, whereas she prefers coffee.
Add que and mientras stops being about timing and starts drawing a contrast between two different people or things — closer to "whereas" than "while."
06 · The sound rule nobody explains
Padre e hijo trabajan juntos.
Father and son work together.
Y becomes e right before a word starting with i or hi — padre e hijo, not padre y hijo. It's there to stop two i-sounds from colliding.
07 · Same rule, the other vowel
Siete u ocho personas.
Seven or eight people.
The same swap happens with o before a word starting with o or ho — siete u ocho, not siete o ocho. Once you hear it, you'll hear it everywhere.
08 · Neither one nor the other
No como ni carne ni pescado.
I eat neither meat nor fish.
Ni...ni brackets both things you're ruling out. It reads naturally once you notice the no at the front holds it together.
09 · Keep the no when the verb leads
No tengo ni hambre ni sed.
I have neither hunger nor thirst.
Because the verb tengo comes first, the no stays in front of it. Drop the no only if ni starts the sentence instead.
10 · Not just... but also
No solo habla inglés, sino también francés.
He doesn't just speak English, but French too.
This pairs sino with también to add a second surprising fact on top of the first — a stronger move than just listing two things with y.
11 · The concession, then the plan
Aunque hace frío, voy a caminar al parque.
Even though it's cold, I'm going to walk to the park.
This is the shape aunque takes most days — a small concession, then what you're doing anyway. Nothing dramatic, just how people actually talk.

Carla
Your grammar teacher for this pack
Nothing here is a worksheet. In the Con Junction lessons you talk, and Carla — who enjoys nuance and gives you a friendly nudge every time you reach for pero where sino fits — keeps setting up the choice live: No quiero té, ___ café versus Me gusta el té, ___ prefiero el café — you pick and justify it out loud. Then she stretches you into no solo… sino también with a sentence about yourself, and into the three ways to give a reason — porque, ya que, como — until each one has its own feel.
Blank mid-sentence and nothing bad happens — she waits. That's the practice, without unnecessary judgement.

Quick answers
After a negation, when you're replacing the wrong thing with the right one: no es alemán, sino austriaco; no quiero té, sino café. Pero just adds contrast: es caro, pero vale la pena.
Mientras alone = while, simultaneous: mientras estudiaba, sonó el teléfono. Mientras que = whereas, contrast: él es tímido, mientras que su hermano es muy abierto. In everyday Latin American speech, en cambio often replaces mientras que.
To avoid two identical vowel sounds: y → e before i-/hi- (padre e hijo, español e inglés), and o → u before o-/ho- (siete u ocho, mujer u hombre). The rule holds even in the most informal speech.
Ni…ni. Keep no when the verb leads: no tengo ni tiempo ni dinero. Drop it when the subjects lead: ni mi madre ni mi padre saben cocinar.
For facts you know are true, it takes the indicative — that's what this badge trains: aunque es caro, lo voy a comprar. You'll also hear the subjunctive for hypotheticals in the wild — igual voy aunque llueva — where igual reinforces the concession.
