Kathy asked, "What is the meaning of in the context of?"
Let's start with the noun context, which is commonly used in two different ways: to talk about surrounding words and to talk about a surrounding situation. Here are the two meanings of context as shown in Merriam-Webster's Learner's Dictionary:
contextnoun
1 : the words that are used with a certain word or phrase to explain its meaning
2 : the situation in which something happens: the group of conditions that exist where and when something happens
Now let's consider the larger phrase, in the context of. This means either:
1) "in the language that surrounds a word or phrase," as in this example:
In the context of this article, the term progressive refers to....
OR
2) "in the conditions that surround an event or situation," as in this example:
In the context of the current recession, job security is becoming very important.
