Hi Jeofergin, your post reminded me of another topic I wanted to address. In my opinion, TOEFL essays use the word “convenient” far too often. In my mind, convenient’s main meaning is to describe something physical which saves us time and makes our life easier - a nearby bus stop, a microwave oven, a fast food restaurant.
But for some reason, TOEFL writers are always using convenient in ways which sound odd to my native ear:
“words which are convenient for essays” - “useful” or “appropriate” would be better
“people move to cities for a more convenient life” - “easier” or “fulfilling” would be better
“Buying a car can help us be more convenient in moving.” - “be more effective in commuting”
“universities are more convenient than the private universities” - “cheaper” or “more affordable”
training machines which are convenient and safe - “effective”
it is likely that you have a rather ordinary and convenient life - “stress free”
There is no doubt that convenient conditions brought us by technology today “productive”
I will avoid multiple financial problems and have a more convenient life thanks to my high salary “fulfilling” or “stress free”
Convenient is usually ok for these situations, but is rarely the best word. Once again, this may be where English learners use a “utility word” instead of using the best word.
