Pairs often confused
en conclusion or enfin in French?
Enfin closes a LIST; en conclusion closes the TEXT. A well-built paper uses both, in that order.
Why
Enfin is the last term of a series opened by d'abord and ensuite: it announces the last argument, not the end of the paper. En conclusion announces the summing up, and nothing new should follow.
en conclusion
En conclusion, cette formule me paraît la plus adaptée.
In conclusion, this option seems to me the most suitable.
enfin
Enfin, je reste à votre disposition pour tout complément.
Finally, I remain available for any further information.
