DEMANDING, TAXING OR TESTING? demanding, taxing aS testing ?
Demanding
is the strongest of these words and
describes tasks and experiences. It is often used with more or most or an adverb that says in what way the
activity is difficult. Taxing is used particularly
in negative statements and to talk about problems or tasks that need (or do not
need) mental effort. Testing describes
experiences but not tasks and is used particularly with time, week or year. * demanding
