The English translation of the French verb démouscailler is “to remove scale, to descale.” It is pronounced as “day-moo-skai-yay” in the infinitive form.

Démouscailler comes from the combination of two words: “démouler,” meaning “to unmold,” and “écaille,” meaning “scale.” It is most often used in everyday French in the Subjonctif Plus-que-parfait tense, which is a compound tense formed with the auxiliary verb “avoir” or “être” in the Imparfait tense and the past participle of the verb.

Here are 3 simple examples of its usage in the Subjonctif Plus-que-parfait tense:

  1. Il fallait que j’eusse démouscaillé le poisson avant de le cuire. (I had to descale the fish before cooking it.)
  2. Si tu avais démouscaillé les carreaux, ils ne seraient pas si sales maintenant. (If you had removed the scale from the tiles, they wouldn’t be so dirty now.)
  3. Elle craignait que nous n’eussions pas démouscaillé le réservoir à temps. (She was afraid that we hadn’t descaled the reservoir in time.)

In all these examples, the Subjonctif Plus-que-parfait tense is used to express a past action that was necessary or desired before another action in the past. In other words, it is used to talk about a completed past action that preceded another past action.
