In this step, we will discuss how to introduce and clarify definitions of key concepts. See the Language focus section in the next tab to find out what language is used to write this part of the Introduction.
The next step that writers often take is introducing or clarifying definitions of key concepts. They may offer their own definitions of the concepts or “borrow” other scholars’ definitions. They may also add their own interpretation of the “borrowed” definitions in the context of their study. When other authors’ definitions are used, these are often integrated as direct quotes (thus quotation marks should be used) or paraphrased, with the sources acknowledged in the references at the end of a sentence. The authors’ names may or may not be mentioned alongside the definition.
Here are step three examples from research articles in different fields.
In which of these examples does the author first give a definition of a concept coined by another scholar and then provide his or her own interpretation of the concept? What ‘defining’ language can you identify in the three examples?
Use this section to learn about typical language that is used to introduce and clarify key definitions for your study. Complete follow-up self-check language activities in the next tab to have more practice with key vocabulary from this section.
Here are some verbs that often feature in definitions:
Be, call, define (as), describe (as), refer to:
Less commonly used defining verbs are signify and designate:
Some defining verbs can be used not only in the active but also in the passive voice, as is shown in the table:
to be |
defined as/ in terms of/ according to called _ concerned with described as referred to known as |
In fact, the use of the passive voice allows the writer to take the focus away from the specific “doer” of an action (e.g., Thomas) to the content of the message. Compare:
Here are some more examples:
There are also some structures that define or explain the function of specific objects, techniques, instruments through the use of a noun + for + V-ing, as in the following examples:
So-called, named, whereby, henceforth (from this time on), that is (= i.e.)
Some adjectives and adverbs can also be used to specify or illustrate what some concepts interjected earlier really mean. Note that “whereby” is often used to replace “by means of which,” “by which” in definitions:
Note that authors can resort to short definitions or clarifications of terms and concepts that appear in the middle of a sentence. These definitions are often separated by commas or placed in brackets, as in these examples:
In some cases, the writers may have to show that there is a certain disagreement on the precise definition of a term or concept. This can be done through providing competing definitions of the term and then indicating which of them the author adopts for the present study. Definitions can, in their turn, be described by authors as accurate/ broad/ clear/ exact/ general/ natural/ precise, or traditional.
The following structures are often used to point to a disagreement in existing approaches to defining a term:
To state a preference for a specific definition, these structures can be used:
