Some words have come into English from Latin more than once, through French or another Romance language at one time and directly from Latin at another. Thus we have pairs like fragile/frail, army/armada, corona/crown, ratio/reason, and rotund/round.

In addition, some words have entered English twice from French, with the result that they have the same source, but different pronunciations reflecting changing pronunciation in French, for example chief/chef (the former a
Electrical discharge machining due to eroded brass particles causing "brass on brass" wire breakage, therefore copper is recommended. Several manufacturers produce EDM machines for the specific purpose of removing broken tools (drill bits, taps, bolts and studs) from work pieces. In this application, the process is termed "metal disintegration machining" or MDM. The metal disintegration process removes only the center of the tap, bolt or stud leaving the hole intact and allowing a part to be reclaimed. Closed loop manufacturing can improve the accuracy and reduce the tool costs Advantages of EDM include machining of: Disadvantages of EDM include: Electrical discharge machining Electrical
