How important are precise and accurate terms?
Every field of knowledge, activity, industry, etc. has its own terminology. For instance, the word “head” means pressure in hydraulics; it is used in politics and business, meaning a leader or a top government executive; it is used in mechanical engineering when they speak about the part of a bolt or screw. When you open a dictionary, you will see a number of other examples, all of them for “head”. It is important to translate a word using the accurate term in the specific field with which the translated document is dealing.
