The English translation of the French verb décaféiner is “to decaffeinate.” It is pronounced as “day-kah-fay-eh-ner.”

Décaféiner is derived from the French word “caféine,” meaning caffeine, and the prefix “de-” which indicates removal or separation.

In everyday French, décaféiner is most often used in the Subjonctif Imparfait tense to express a hypothetical or uncertain action in the past. It is formed by using the present tense form of the subjunctive verb “décaféiner” and adding the imperfect subjunctive endings “-asse, -asses, -ât, -assions, -assiez, -assent.”

Three examples of décaféiner in the Subjonctif Imparfait tense are:
