I always hear my French teachers say “entre guillemets” followed by some phrases. I asked my friends what does it mean? They told me that they use it when talking about something not true. However, I did not really understand all the times I heard it.
For example, “Entre guillemets, cette méthode est la meilleure”. So, it implies that this method is bad, doesn't it?
Could anyone please explains it along with some examples?
