Q: I'm talking about an incurable disease which is a lifelong affliction but is not fatal. Usage - She is suffering from a ____________ illness. I can't use terminal here because terminal means 'predicted to lead to death, especially slowly; incurable.'.

A: chronic From the Oxford English Dictionary (OED) Of diseases, etc.: Lasting a long time, long-continued, lingering, inveterate; opposed to acute OED cites as an example: 1994 Jrnl. Internal Med. 236 685 A 23-year-old female student exhibited all the characteristics of chronic factitious disorder with physical symptoms (Munchhausen's syndrome): deliberate simulation of illness, peregrination, fantastic pseudology and dramatic circumstances on admittance.

Q: Is it ok to talk about 'personal PCs', in the sense of distinguishing it from a work PC? Or would it be regarded as a case of RAS Syndrome?.

A:
Though the word personal is repeated in the expansion 'personal personal computer', the two repetitions use different meanings of the same word. The first personal means 'owned or used by a specific single person' (definition 1 here), while the second indicates 'designed to be used by a single person' (definition 2 here, again). Both instances are required to convey the full idea and thus are not redundant. Consider the following examples spelled out in full: Personal PC: personal personal computer, (the usual case of a personal computer owned by a person) personal mainframe computer (I have a Cray in my bedroom), Public PC: public personal computer (a PC that is installed in a kiosk usable by anybody)
