When the boss says jump, the question is usually ‘how high’.
Not that it’s possible for many of us with a challenging centre of gravity to get much elevation.
High generally means height, how far something rises above ground level, is above our heads.
That plane flies very high in the sky.
Then there’s another meaning, increased intensity, such as a high temperature, a high fever, but my favourite is, a high dudgeon.
I’m still to get a definition on what a dudgeon is.
We have secondary schools here that we call high schools. Make of that what you will
And in the idiomatic world, flying high means we are very happy, and when were left high and dry then not so much. Unless it related to a ship, in which case a lot of people would be unhappy.
We can use high just about everywhere, high hopes, high ceilings, feelings that run high, a high chair for toddlers of course, high speed which may cause s crash and land you in a high security prison.
This is not to be confused with just plain hi which is a universal greeting.
But there is another, hie, which has a more obscure meaning, to hasten or go quickly.
