C2 Discourse connectors and register

To write and speak at an advanced level, link your ideas with precise connectors rather than just y and pero.

sin embargo / no obstante	however / nevertheless
por lo tanto / por consiguiente	therefore
además / asimismo	moreover
aunque / a pesar de que	although
en cuanto a	as for / regarding
por un lado… por otro lado	on one hand… on the other
en resumen / en definitiva	in short

Register matters: usted, the passive-se, and connectors like no obstante signal formal writing; tú, pues and o sea mark casual speech.
