A small comment. The word "tâche" (task) derives from medieval Latin "taxa", so where is the "s" it replaces? It's there. In manuscripts "x" often replaces "sc", so "taxa" is just a shorthand way of writing "tasca." "Task" in English derives from the same word.
That helps us to distinguish between "tâche" and "tache" (stain), which ultimately derives from the German "taikns" (spot, sign). Just remember that tâche is related to "task" and tache isn't.
