I have the following sentence:
What this program does is produces fluorescent proteins in a rhythmic fashion and generates a small molecule that allows bacteria to communicate and synchronize, as you're seeing in this movie.
What does 'in a rhythmic fashion' mean?
The Cambridge Dictionary gives the following definitions for fashion:
fashion noun (POPULAR STYLE)
A2 [C or U]: a style that is popular at a particular time, especially in clothes, hair, make-up, etc.:
- Long hair is back in fashion for men.
- Fur coats have gone out of fashion.
- a programme with features on sport and fashion
- She always wears the latest fashions.
fashion noun (MANNER) › [S] a way of doing things: - The rebel army behaved in a brutal fashion.
It is not clear how either of these definitions applies to the current usage. Or if one of them doesn't, it's not clear why it is that one that does!
