Your Thoughts And Ideas Are More Important Than English
In normal usage, simple words are preferred because the aim is to get your message across to the maximum people with minimum effort.
But in IELTS, you should try to use difficult but appropriate words.
Why so?Because in IELTS, out of four grading criteria one is Lexical Resource and this means the number and variety of different words you know and can use effectively.
- means to an end: something done to achieve something else
- compromise: to reduce the quality, value, or degree of something.
- appropriate: suitable or fitting for a particular purpose, person, occasion, etc.
