"Undocumented." "Obamacare." "Pro-life."
According to NPR's style guide, these words are to be avoided — or used sparingly — by NPR reporters and hosts when discussing the issues in which they are likely to come up (immigration, health care, abortion rights). But sharp listeners and readers note that all have been used in recent weeks, either on-air or online (by staff, not just by people being interviewed).
