assistant
The word 'assistant' in French is used in the same way as in English, to refer to someone who assists or helps another person, often in a professional context. It can be used as a noun or an adjective. For example, 'un assistant de recherche' (a research assistant), 'une assistante médicale' (a medical assistant), or 'assistant à la conférence' (assisting at the conference).
I am the professor's assistant.
In this sentence, 'l'assistant du professeur' means 'the professor's assistant'. In French, the possessive 'du' is used, which is a contraction of 'de' (of) and 'le' (the).
He works as an assistant in a company.
The phrase 'Il travaille comme assistant dans une entreprise' translates to 'He works as an assistant in a company'. 'Comme' is the French word for 'as', used to indicate role or function.

In this phrase, 'L'assistant a préparé le matériel pour le cours', 'a préparé' is the third person singular past tense of the verb 'préparer', which means 'to prepare'. 'Le matériel' means 'the materials' while 'pour le cours' means 'for the course'.
