Questions & Answers about Le professeur souligne les fautes d’orthographe avec un stylo rouge.

Why is it Le professeur and not Un professeur?

French has two main types of articles:

• Definite article: le / la / les = the
• Indefinite article: un / une / des = a / an / some

Using le professeur suggests:

• We are talking about a specific teacher that the speaker and listener both know (for example, the teacher of this class).
• Or we are talking about the teacher in a general, habitual way:
  Le professeur souligne les fautes… = The teacher (in general) underlines the mistakes… (this is what he/she typically does).

Un professeur souligne les fautes… would sound more like:

• A teacher underlines the mistakes… (introducing some random or new teacher, not one already known from context).

So le matches English “the” here: a particular or contextually known teacher.
