Business writers like to use the words ‘high’ and ‘low’ indiscriminately. Numbers can be high or low, but physical things such as ships can’t (except in the Panama Canal locks). Similarly, they use the verbs ‘rise’ and ‘fall’ – the process of becoming high or low – too much. If you use such words for things other than numbers, you give the impression that you aren’t thinking about the real world.
I recently saw a shipping report declare that the fleet will “rise”, giving a mental picture of ships levitating, when the writer meant ‘grow’ or ‘expand’.
Once the habit is formed, these words drive out all others, behaving like invasive species and creating an inert ecosystem of language. A recent report spoke of “high competition”. Would you say that companies are ‘competing highly’? Of course not. Competition can be strong, aggressive, vigorous, stiff, stern and many other things. It can’t be high.
Moral: Never forget literal meanings when using words figuratively.
