Yesterday I presented the ASVAB vocabulary word “vague”. Do you know what “vague” means? Vague is one of the over 500 words I have included in my book, The ASVAB Tutor’s Word Knowledge and Paragraph Comprehension Study Guide. As an ASVAB tutor, in my ASVAB prep course I see the importance of reviewing common ASVAB vocabulary words as well as prefixes, root words, and suffixes . The word “vague” does not have a prefix, root word, or suffix. Do you know what it means? It means unclear. If someone give you a vague answer, it means an unclear answer. To prepare for the ASVAB, make sure you review vocabulary, reading, and math to help improve your ASVAB score.
