Notes on Meaning

• While the original military sense (a hostile attack) is valid, the word is most frequently used in modern English in a figurative sense. It describes progress or advances, often competitive, into a new area (like a market, field of study, or social sphere). The connotation is often of a challenging or hard-won advance against existing competition or resistance.
