Prepositions
Each of the six has a learnable job. You can’t guess which one goes with which verb: soñar con, insistir en, buscar with nothing. It arrives with the verb.

A real call: our founder, Shaen, talking with Diego for eleven minutes about why he built Project Fluency. Rewind pulled out every moment he tripped, in his own voice, next to Diego’s fix from the same call.
Shaen with Diego · Friday 2 October · a real call00:00 / 11:26
Diego, in the same call — “Si no hubiera invitado a Yudy. En español, las personas llevan esa ‘a’ antes.”
Diego, in the same call — “Casi — si Jezza no hubiera tomado. Después de ‘si’, siempre hubiera, nunca habría.”
Diego, in the same call — “Si no hubiera salido de mi trabajo — necesita esa ‘de’ ahí.”
Diego, in the same call — “Casi — habría preguntado al inversionista. Con el artículo ‘al’.”
Philippe, in the same call — “Je suis allé au cinéma. Aller, c’est avec être : je suis allé.”
Philippe, in the same call — “Presque… je suis né à Chicago. Naître aussi, c’est avec être.”
Philippe, in the same call — “Je suis resté à la maison. Rester, c’est être.”
Philippe, in the same call — “Ah, là c’est avoir : j’ai marché deux heures. Marcher prend avoir.”
Giulia, in the same call — “Mi piace la pizza napoletana! È la pizza che piace a te.”
Giulia, in the same call — “Mi piacciono i musei: sono tanti, quindi piacciono.”
Giulia, in the same call — “A mia sorella piace il calcio. Ci vuole la a, a chi piace.”
Giulia, in the same call — “Mi sono piaciute le lasagne. Al passato piacere va con essere, e segue le lasagne.”
James, in the same call — “It’s raining a lot, yeah. English needs the it: it’s raining.”
James, in the same call — “It’s very important for your job. Even when it means nothing, English wants it there.”
James, in the same call — “It’s your first time? Welcome. It’s my first time, with the it.”
James, in the same call — “It was a long week, I bet. It was, with the it up front.”
Marcelo, in the same call — “Quase! ‘Amigos’ é masculino plural, então é ‘muitos amigos’. O adjetivo segue o gênero.”
Marcelo, in the same call — “Quase! ‘Bom’ é adjetivo, mas aqui precisa de advérbio: ‘bem’. Eu dormi bem ontem à noite.”
Marcelo, in the same call — “E lembra: depois de ‘Rio’ precisa de preposição. Eu viajei para o Rio no ano passado.”
Marcelo, in the same call — “Quase! ‘Muito bem’ é advérbio. Aqui você precisa de adjetivo pra descrever a canção: ‘uma canção muito boa’.”That one habit, the little words a and de, follows you into four places. Pick one.
La última vez lo produjiste solo, sin ayuda — “si hubiera tenido, habría hecho” tres veces seguidas. Hoy lo sacamos del contexto de negocios. ¿Empezamos?
Last time you did it on your own, no help: three times in a row. Today we take it out of business. Shall we?
It picks up where you left off. Diego opens the next call on the last one and listens for the little words. When an a or a de slips, he catches it right there, without a lecture.

plays the moment back in your own voice, then Diego’s fix
Most verbs make the past with avoir. A short list lives in the house of être. They are verbs of coming, going, staying and being born: je suis allé, je suis resté, je suis né. Marcher stays with avoir.
plays the moment back in your own voice, then Philippe’s fix
In Italian the thing you like is the subject: it does the pleasing. One thing, mi piace; more than one, mi piacciono; someone else, a mia sorella piace.
plays the moment back in your own voice, then Giulia’s fix
Spanish lets the subject drop: es importante, llueve. English never does: weather, time and opinions all start with an empty it. It’s raining, it’s late, it was a long week.
plays the moment back in your own voice, then James’s fix
Bom describes a thing and agrees with it: um café bom, uma canção boa. Bem describes how you do something and never changes: dormi bem.

Shaen, «habría preguntado al inversionista»: el «al» marca que el inversionista es a quien se dirige la pregunta, el objeto indirecto. La preposición viene con el verbo, no se adivina. En esta llamada te pasó tres veces: invitar a, salir de, preguntar a. Apréndelos juntos.
After every call, they leave you a note: the one thing worth keeping, in their own words. Turn it over for the lines you said.
Diego’s note, after the real call in RewindI can join a conversation on familiar topics without preparation

Ce pingouin vit sur les îles Kerguelen. Les îles Kerguelen sont dans l'océan Indien, très loin au sud. Il n'y a pas de ville sur ces îles. Elles sont à plus de 3 000 kilomètres de tout endroit habité en permanence. C'est un endroit très difficile à visiter. Le vent et le froid y sont très forts.
