I must relieve myself of this particular one before I build up too much steam as it is starting to set my teeth on edge! The word in question is "discrete".
In particular it seems to be used by people claiming to have an excellent grasp of English and pulling other people up!For example in threads claiming annoyance at people using their/there instead of they are etc.
OK discrete - distinctly separate
discreet - modest etc.
Thanks I feel a lot better now.
