Four French ‘air’ expressions

We look at four French expressions that feature the word ‘air’ and explain where they come from. 

Brasser de l’air (literally ‘to brew the air’):

This expression means to say or do a lot in order to gain something but without success - for example, if someone makes a big show of being busy, but gets nothing done.

It comes from the idea that if one were to ‘brew air’, one would put in a lot of effort and receive nothing of substance in return.

You can also replace 'air' with 'vent' (wind): brasser du vent. 

Avoir les quatre fers en l'air (literally ‘to have all four irons in the air’):

This expression means to find oneself on one’s back after falling over and has been in use since the early 19th Century.

The fer (‘iron’) refers to fers à cheval – horseshoes. When a horse falls over, all four of its horseshoes become visible as it lays on the ground. The expression is now used for humans or any other animal.

Changer d'air (literally 'to change air'):

People in France use this expression to say that they are looking for a change of scenery, and feel the need to get away from their day-to-day routine and surroundings. 

It is linked to the idea of describing a new and refreshing environment as a 'breath of fresh air.' 

Être dans l'air du temps (literally: to be in the air of time)

This expression is used to describe something fashionable, topical and in keeping with the times. 

It can refer to a variety of contexts and situations, but is often anchored around a theme or subject that everyone is talking about. 

In this context, 'air' is employed in its figurative sense, referring to an atmosphere. It can also represent a feeling, ambiance or general mood. 

Synonyms include: être en phase avec son époque, and être à la mode.
