Overview
I'll be there in 5 alors que t'as même pas encore quitté la maison ? Ou peut-être que t'as posté I'm going to start my fitness journey sur Instagram tout en mangeant une pizza ? Si c'est le cas, tu utilises déjà le futur en anglais.will et be going to. La plupart des apprenants utilisent will pour tout. C'est facile, non ?I will finish the report alors qu'il devait être rendu hier. On dirait que tu viens d'y penser à l'instant.will et be going to pour exprimer ces différentes ambiances.Will, c'est ton pote réactif et rapide. Be going to, c'est ton pote organisé qui prévoit tout. Les deux regardent vers l'avenir, mais ils voient le monde différemment.How This Grammar Works
will. S'il a basculé *hier*, utilise be going to.It's going to rain, tu as une preuve sous les yeux.I think humans will live on Mars, tu ne fais que deviner. C'est comme la différence entre une appli météo et une boule de cristal. L'une utilise des faits, l'autre des intuitions.
Formation Pattern
will, place-le simplement avant la base verbale.
be going to, tu dois conjuguer la partie be.
am, is ou are selon la personne.
going to sonne souvent comme gonna. Évite juste d'écrire gonna dans une lettre de motivation, sauf si tu veux rester au chômage !
When To Use It
will pour les décisions rapides. Tu es dans un café et le serveur te demande ta commande. Tu dis I'll have a latte, please.I'll always love you sonne mieux que I am going to love you.be going to pour les projets. Si tu as réservé un vol pour Londres, dis I'm going to London. Si tu dis I'll go to London, on dirait que tu pourrais changer d'avis si une meilleure soirée se présente.My phone is going to die. Tu as la preuve sous les yeux sur l'écran.
Common Mistakes
will pour les plans déjà fixés. Si tu as une réunion Zoom à 14h, ne dis pas I will meet them at 2. Ça donne l'impression que c'est une idée soudaine. Dis plutôt I'm going to meet them. Une autre erreur classique est d'oublier le am/is/are dans going to. I going to eat est une faute typique. On dirait un homme des cavernes. I am going to eat, c'est bien mieux. Enfin, évite d'utiliser will pour des choses qui vont arriver très bientôt à cause d'une preuve physique. Si un vase vacille sur une étagère, dis It's going to fall!, pas It will fall. La deuxième option ressemble à une malédiction lancée par un sorcier.Contrast With Similar Patterns
I'm meeting Sam tonight. C'est encore plus sûr que going to.I'm going to meet Sam est un projet, mais tu n'as peut-être pas encore choisi le resto. I'll meet Sam, c'est ce que tu dis quand Sam t'appelle d'un coup pour te proposer de sortir.Quick FAQ

Meanings
English uses different structures to talk about the future depending on whether we are predicting, planning, or deciding in the moment.
Spontaneous Decisions
Deciding to do something at the exact moment of speaking.
“The phone is ringing. I'll get it!”
“I'm tired. I think I'll go to bed now.”
Prior Plans and Intentions
Something you have already decided to do before the conversation started.
“We are going to get married in June.”
“I'm going to start a new job on Monday.”
Predictions based on Evidence
Predicting the future because of something we can see or feel right now.
“Watch out! You're going to drop that vase!”
“I feel terrible. I think I'm going to be sick.”
Predictions based on Opinion
Predicting what we think or believe will happen, without physical evidence.
“I'm sure you will pass the exam.”
“People will live on Mars one day.”
Promises and Offers
Using 'will' to commit to an action for someone else.

Smart Tips
Always use 'I'll have...' rather than 'I'm going to have...'. It sounds more decisive and natural to the waiter.
Use 'going to'. If you see a person running very fast toward a door, say 'He's going to open the door'.
Use 'will' to show commitment. 'I will help you' sounds like a stronger promise than 'I am going to help you'.
Avoid 'gonna' and even 'I'll'. Write out 'I will' or 'We are going to' to maintain a professional tone.
Prononciation
Contraction of Will
The 'll' sound is often a 'dark L'. It sounds like a small 'ul' sound at the back of the throat.
Gonna
In fast speech, 'going to' becomes 'gonna'. The 'to' sound disappears completely.
Spontaneous Will
I'll ↗ GET it!
Emphasis on the action decided suddenly.
Going To Prediction
It's going to ↘ RAIN.
Falling intonation on the final word for a statement of fact/evidence.
Mémorise-le
Moyen mnémotechnique
Will is for the 'Wheel' of fortune (luck/spontaneous), Going To is for the 'Goal' (planned).
Association visuelle
Imagine a lightbulb turning on for 'Will' (a sudden idea). Imagine a calendar with a circled date for 'Going To' (a plan).
Rhyme
If you plan it in your head, 'Going To' is what is said. If you decide it on the spot, 'Will' is what you've got!
Story
A man sees a woman struggling with a suitcase. He thinks, 'I'll help her!' (Will - spontaneous). Later, he tells his wife, 'I'm going to buy a new suitcase for our trip' (Going to - plan).
Word Web
Défi
Look around the room. Find one thing that is 'going to' happen (e.g., a candle burning out) and make one 'will' decision (e.g., 'I'll drink some water').
Notes culturelles
British speakers may use 'shall' for offers ('Shall I open the window?'), whereas Americans almost always use 'should' or 'will'.
The use of 'gonna' is extremely prevalent in all but the most formal spoken contexts. Using 'going to' in a casual bar might sound slightly stiff.
Using 'will' for a promise is culturally significant. 'I will' is the standard response in marriage ceremonies.
'Will' comes from Old English 'willan' (to wish/want). 'Going to' developed later as a way to use a verb of movement to show a path toward a future action.

FAQ (8)
Sometimes, especially for general predictions like 'It will rain' vs 'It's going to rain'. However, for plans vs. spontaneous decisions, they are not interchangeable.
It is a phonetic spelling of how people speak. It is not used in formal writing, but it is very common in songs, movies, and texts.
English is a stress-timed language. We prefer to contract unstressed words like 'will' to keep the rhythm of the sentence.
If you are in doubt, 'going to' is often safer for personal intentions, while 'will' is safer for general facts.
Yes, always. Without the 'be' verb, the sentence is grammatically incomplete.
Yes, for general predictions ('It will be cold in winter'). Use 'going to' if you see clouds right now.
In modern English, 'shall' is mostly used for polite suggestions ('Shall we dance?') or very formal documents.
Move the 'be' verb to the front: 'Are you going to...?'
