Overview
pero, sin embargo y no obstante. En inglés, los dos pilares fundamentales para esto son but y however.but donde deberías usar however, podrías sonar demasiado informal o incluso gramaticalmente incorrecto. Por el contrario, si usas however en una conversación casual, podrías sonar innecesariamente rígido o pomposo.But es una conjunción coordinante (Coordinating Conjunction)but pertenece al grupo de las llamadas FANBOYS (for, and, nor, but, or, yet, so). Su función principal es unir dos partes de una oración que tienen el mismo peso gramatical. En español, equivale casi exactamente a nuestro pero.but, estamos creando un puente directo entre dos ideas dentro de la misma oración. Es como si pegáramos dos piezas de un rompecabezas. La relación es tan estrecha que la segunda idea se siente como una extensión natural de la primera, aunque sea para contradecirla.I love the beach, but I hate the sand.(Amo la playa, pero odio la arena).
However es un adverbio conjuntivo (Conjunctive Adverb)However no es una simple conjunción; es un adverbio que funciona como conector lógico. En español, su equivalente más cercano es sin embargo o no obstante.but, however no pega las oraciones físicamente; más bien, actúa como una señal de tráfico que indica que la siguiente oración independiente va a contrastar con la anterior. Es una transición más pesada y formal. Gramaticalmente, however tiene mucha más libertad de movimiento dentro de la oración que but, algo que veremos más adelante.butune dos cláusulas independientes en una sola oración larga.howeverconecta la relación lógica entre dos oraciones que suelen estar separadas por un punto o un punto y coma.

Tienes tres formas principales de usarlo:However en mayúscula y se coloca una coma inmediatamente después.The company faced many challenges. However, they reached their goals.
;).The results were inconclusive; however, we decided to proceed.

Preguntas frecuentes (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.
