Comprehension means mentally grasping. To grasp is to 'get' or understand something.
You may find this quiz, at first look, quite difficult. However, the key to understanding language is to look at the whole sentence or section. From there, you can usually work out what a word means even if you've never come across it before. If you want to practise this skill, then read lots of books ~ not only fiction, but non-fiction too. Of course, if a word has you completely stumped, you can always look it up in a dictionary. Either way, your vocabulary bank will be ever-growing!
In this last 11-plus English comprehension quiz, you will get the chance to see how good your vocabulary is: read the questions carefully; there is enough information to enable you to select the correct answers.
