Definition
'Bas bleu' is the French equivalent of 'bluestocking,' referring to an intellectual or literary woman. It carries the same connotation of someone who is perhaps too focused on intellectual pursuits. Think of it as the Parisian version of a bookworm. It subtly suggests that these women might be neglecting other, more traditionally feminine, interests. It's like calling someone 'bookish' but with a touch of old-world charm. The term is less common in everyday English but provides a touch of sophistication.
