You might regard words as dependable things, that never do anything more tricksy than linger overly long on the tip of your tongue. But beware – don't let them gang up on you, or you'll be left with phrases.
George Orwell (1946) wrote in ‘Politics and the English language’ that:
“prose consists less and less of words chosen for the sake of their meaning, and more and more of phrases tacked together … the ready-made phrases come crowding in. They will construct your sentences for you – even think your thoughts for you, to a certain extent – and at need they will perform the important service of partially concealing your meaning even from yourself.”(pp. 145, 152, italics in original)
