Overview
but et however.mais, qui est un véritable couteau suisse. On l'utilise partout : à l'oral, à l'écrit, en début de phrase, au milieu, de manière formelle ou décontractée. En anglais, c'est un peu plus subtil.but à tout bout de champ, ton anglais risque de paraître un peu répétitif ou trop informel dans un contexte professionnel. À l'inverse, si tu places mal however, ta phrase sera grammaticalement incorrecte, ce qui est une erreur classique chez nous, les francophones.But et however servent tous deux à introduire une opposition, mais ils ne jouent pas dans la même catégorie grammaticale. But est une conjonction de coordination, tandis que however est un adverbe de liaison (ou adverbe conjonctif). Cette distinction, qui peut paraître technique au premier abord, est cruciale car elle détermine la ponctuation que tu dois utiliser et la place du mot dans ta phrase.but (La conjonction)But fait partie d'un petit groupe de mots que les anglophones appellent les FANBOYS (*for, and, nor, but, or, yet, so*). Son rôle est de relier deux éléments de même valeur grammaticale. Le plus souvent, il relie deux propositions indépendantes (des phrases qui pourraient exister seules) pour en faire une seule phrase complexe.but crée un lien direct et immédiat. C'est le cousin germain de notre mais. Il indique que ce qui suit va tempérer ou contredire ce qui vient d'être dit, sans pour autant marquer une rupture nette.I wanted to call you, but I lost my phone.(Je voulais t'appeler, mais j'ai perdu mon téléphone.)
however (L'adverbe)However est plus proche de nos mots cependant, pourtant ou toutefois. Contrairement à but, il ne sert pas techniquement à coller deux phrases ensemble. C'est un adverbe qui commente la relation logique entre deux idées distinctes.but est un pont qui relie deux îles, alors que however est un panneau de signalisation sur la deuxième île qui indique : "Attention, ce qui est écrit ici est en contraste avec l'île précédente". Parce que c'est un adverbe, il est beaucoup plus mobile. Tu peux le placer au début, au milieu ou même à la fin d'une proposition, ce qui est impossible avec but.But introduit souvent un contraste attendu ou léger. However introduit souvent un contraste plus fort, plus formel, ou une information qui vient contrecarrer une attente importante.however sera ton meilleur allié pour marquer tes transitions avec élégance.butbut relie deux propositions complètes (Sujet + Verbe), on place presque toujours une virgule avant but.but Phrase B. | The hotel was expensive, but the service was poor. |but Idée négative. | She is very talented, but she lacks discipline. |He is small but strong.howeverHowever demande une ponctuation plus lourde. Tu as trois options principales :however, suivi d'une virgule.The marketing campaign was creative. However, it didn't reach the target audience.

FAQ (8)
Yes, you can, especially in informal writing or speech. However, in very formal academic essays, it is better to use `However` or `Nevertheless`.
The comma signals a pause, showing that `however` is a transition word (conjunctive adverb) and not part of the subject or verb.
Yes, significantly. `But` is neutral and common in speech, while `however` is the standard for professional and academic writing.
Usually, no. It would be redundant. Choose the one that fits your punctuation and register.
A comma splice is when you join two full sentences with only a comma. Using `however` with just a comma (e.g., 'I'm tired, however I'm going') is a classic comma splice.
Yes! For example: 'The food was expensive. It was delicious, however.' This is common in spoken English.
If it is joining two independent clauses (full sentences), yes. If it is just joining two words (e.g., 'small but strong'), no comma is needed.
They are very similar, but `nevertheless` is even more formal and emphasizes that something happened *despite* the previous point.
