Which sentence do you think is correct; "It was a sunny day and the wind was cold?" or "It was a sunny day, but the wind was cold?" To tell which sentence is correct, you must understand the rules and usages of conjunctions. A conjunction connects two or more sentences or clauses. There are three types of conjunctions: coordinating, subordinating and correlative. There are seven coordinating conjunctions. They are for, and, nor, but, or, yet and so. What is the difference between the conjunctions 'and' and 'but'? We use 'and' to add statements that are similar. We use 'but' to suggest a cotnrast. We cannot say "It was a sunny day and the wind was cold" because the two statements connected by 'and' are not similar. Here the second statement (The wind was cold) suggests a cotnrast with "It was a sunny day". Since 'but' expresses cotnrast, the correct sentence is "It was a sunny day, but the wind was cold". A comma is usually used with but when expressing a cotnrast. What is the difference between 'but' and 'yet'? The conjunction "yet" is very similar to "but". 'Yet' means something like "but at the same time". Example: The sauce was sweet yet had a spicy flavour to it. A subordinating conjunction is a word that connects a main clause to a subordinate clause. The common subordinating conjunctions are as, because, since, though, unless, if, as, when, that etc. Students often confuse the usage of 'because' and 'so that'. We use because to give the reason for something: I took a taxi because I was in a hurry. We use so that and in order that to talk about the purpose of an action: I took a taxi so that I would arrive on time. The conjunction in order that is more formal than so that. In each of the following questions, find out which part of the sentence has an error. 1. Although they listen to me (a)/ but their actions (b) / prove otherwise (c) / No error (d) 2.

You need to do the practice test and study the rules to clear all confusions. Practice is the key to success.
