basic vocabulary for engineering

BASIC VOCABULARY FOR ENGINEERING(list and exercises)

Please note these vocabulary exercises have been devised for a particular course with French students. This entails the following consequences:

a/ the vocabulary I have chosen to teach is what may be called "general engineering vocabulary" with a very slight emphasis on mechanical engineering. Highly specialised vocabulary has deliberately been left out;

b/ my students are (pre) intermediate, which means I have tried to avoid including both very basic and also advanced words/ phrases;

c/ naturally I have used my students' knowledge of French as a stepping stone. As a result,

* many words do not appear in the list since they are very similar in both languages (e.g. to install / installer - a

plan / un plan - precise/ précis, etc.); * conversely, I have insisted on what we call "faux amis" ( false friends,i.e. words which look alike but have

different meanings), for instance to control, to achieve, etc; * some exercises are based on translation from or into English.

If you decide to use these exercises I know you 'll have a lot of re-writing to do, but I do hope this list

may be useful.
