Yep, another of those interesting little words that mean more than it appears.
Aside from the fact it is the air that we breathe, it can also be used to describe music.
It can be a breath of fresh air, though it’s hard to say where in this ever increasingly polluted atmosphere than we could literally draw one, except on a mountain top, where conversely it would be hard to breathe at all.
Have the air sucked out of us, well, that literally isn’t possible unless some madman comes up with a weird sort of vacuum cleaner, but that might be an episode for the X-Files.
He had an air about him, or her, as the case might be, which might refer to a sort of deference or manner. There again that air might be one of boredom, which is what a lot of students seem to have in class.
Sorry, been a teacher, and know well the expressions on their faces. Had one myself once, and finished up on the end of a chalkboard eraser. Yep, in the good old day’s teachers used to chuck stuff at us recalcitrant students to get our attention, and not undergo a storm of protest from irate parents.
These days those same parents would most likely air their grievance, opinion, or view to the headmaster.
I’m guessing that same headmaster would be wishing those same parents to vanish into thin air, though I’m not sure how that would be possible.
And lastly, television stations air shows.
Weird, eh, how such a simple word can be used in so many contexts.
