The proper use seems to me to be as a designation for a body of words, not for members of a body.
This question, for instance, strikes me as an appropriate use:
How to memorize 5500 English words within the shortest time?
I am considering to appear for GRE. For this purpose, I have bought a vocabulary book containing 5500 words.
It must be mentioned that I work 12 hours per day and thus I have limited free time.
My questions are:
- What major factors apply rapid study?
- Is learning by vocabulary an affective technique to prepare specifically for GRE test?
- If so, how many days would be a realistic target?
- If not, what learning techniques let me prepare myself within the shortest possible period of time?
Another appropriate use of the tag was on the question Card game vocabulary (which was closed as Off Topic). The other questions with this tag, however, are common-or-garden-variety word requests, and should be retagged.
