I'm not quite sure to tell you the truth since I don't know what the poster is advertising. My guess is that 'English in the air" might be referring to an open air event; but, then again, that's just a guess.Originally Posted by Hong Kong Chinese
be "in the air" has two meanings (note, there's a BE verb):
1) undecided
Ex: My future is up in the air. (I've haven't decided what I'm going to do when I graduate from school).
2) the smell or feeling of the seasons changing
Ex: Spring is in the air. (I can smell Spring)
Ex: Winter is in the air. (I feel cold)
There's also "love is in the air".
