fusion

OBS: According to Dean Foust, the author of the article from whence this quote has come, the term roll-ups is ""Wall Street parlance for the merger of several limited partnerships into a single, publicly traded company.
CONT: When real estate and oil-drilling partnerships turn sour, promoters inevitably turn to two things; Rolaids and 'roll-ups'.
OBS: This is a semantic modulation. The term roll-up is not new to the English language, but its meaning in this context is. It is a general term that has been adapted to fit this new domain-- that of Business Affairs and Finance. Because its meaning has been modified, it can also be perceived as an extension of sense.
