We use conjunctions such as \u2018and\u2019 and \u2018but\u2019 to build grammatical sentences, which helps us to express ourselves clearly.\n\nIn this post, then, we look at three conjunctions that you may need to use in your academic writing: \u2018as far as\u2019, \u2018since\u2019 and \u2018even though\u2019.\nAs Far As (To the Degree That)\nUsed as a conjunction, \u2018as far as\u2019 means \u2018to the degree or extent that\u2019. We therefore use it to qualify statements that apply only under particular conditions. A phrase like \u2018as far as we know\u2019, for instance, would usually signal that something is based on incomplete information:\nThe experiment poses no risk as far as we know.\nHere, then, we\u2019re saying that the first part of the sentence is true to the best of our understanding. But including \u2018as far as\u2019 here suggests that our knowledge of the situation is less than perfect or complete.\n\nIn addition, \u2018as far as\u2019 is a subordinating conjunction when used like this. And as with all subordinating conjunctions, this means we use it to link a dependent clause (\u2018as far as we know\u2019) to an independent clause (\u2018The experiment poses no risk\u2019) when forming a complex sentence.\nSince (Time and Justification)\nAnother subordinating conjunction, \u2018since\u2019 has two distinct uses. The first is to specify that something began or occurred after a particular point in time:\nSince learning to dance, I\u2019ve felt much more graceful.\nHere, for example, by using \u2018since\u2019 we\u2019re saying the speaker began feeling graceful only after learning to dance.\n\nThe second main use of this term is to introduce a reason or justification for something. For example, we might say:\nSince we are interested in how people subjectively perceive their retail experiences, we have adopted a qualitative research approach.\nIn this example, \u2018since\u2019 joins a clause specifying the reason for picking a research approach to the main clause identifying the approach chosen. It therefore works like the term \u2018because\u2019.\nEven Though (Despite the Fact That)\nFinally, we can use the term \u2018even though' to introduce a contrast. This makes it like saying \u2018despite the fact that\u2019. For instance:\nEven though he was completely deaf by 1820, Beethoven began writing his final complete work, the Ninth Symphony, in 1822.\nHere, we use 'even though' because we'd usually expect deafness to curb one's musical career, but Beethoven defied that expectation.\n\nOne key feature here is that, compared to similar terms like \u2018although\u2019 and \u2018though\u2019, \u2018even though\u2019 is more emphatic. We would therefore use it to introduce a contrast that is particularly surprising or unexpected (such as Beethoven\u2019s ability to compose music despite having lost his hearing).
