The proposed volume of the Illustrated Technical Dictionary in Six Languages ​ ​ is devoted to cars, motor boats, balloons and aircraft, i.e. the newest and most promising branches of technology at the beginning of the 20th century. All these means of communication were included in one volume because they are powered by engines and do not need a special path; they are in mutual close communication also because their further development is largely due to the improvement of high-speed internal combustion engines. The proposed volume mainly includes expressions related to automotive technology.
