What is the role of modal verbs in academic writing?

Garret McTerry

Modal verbs play an essential role in academic writing. They are used to convey different degrees of certainty, obligation, possibility, ability, and permission. Academic writing requires the use of precise and clear language, and modal verbs help us achieve this by adding nuances to our statements.

One of the main functions of modal verbs in academic writing is to express probability and certainty. For instance, words like 'may', 'might', 'could', 'would', and 'should' are used to show the level of likelihood of a certain outcome or event. These modal verbs are frequently used in hypotheses and conclusions to signify that the writer is not completely sure about the stance taken. On the other hand, 'will', 'must', 'shall', and 'ought to' indicate higher levels of certainty and are more indicative of an author's confident stance.

Furthermore, modal verbs are also used to convey obligation and necessity. Words like 'must', 'should', and 'have to' are used to show that something is mandatory, whereas, 'need to', 'ought to', and 'should' indicate that something is recommended but not required. Distinguishing between mandatory and optional actions is essential in academic writing to ensure that the reader understands the magnitude and significance of the statement. Additionally, modal verbs are also used to express permission and ability. 'Can', 'could', and 'may' are used to indicate permission, whereas 'can', 'could', and 'be able to' are used to specify the capacity to carry out a particular action.

Modal verbs also differ in their tenses; some are present, while others are past. The present modal verbs are used to indicate present time obligations, abilities, expectations, and possibilities. On the other hand, past modal verbs are used to express past-time obligations, abilities, and possibilities.

In addition, when writing academically, your use of modal verbs could affect the tone, style, and audience of your work. Overuse of modal verbs like 'may' or 'could' could give your work an indecisive tone, while excessive use of modal verbs like 'must' or 'should' could make your work appear prescriptive. Therefore, it is essential to use modal verbs appropriately and effectively in line with your writing purposes.

In conclusion, modal verbs are an essential element of academic writing. They serve to indicate probability, obligation, permission, and ability, and differentiate between optional and mandatory actions. However, to use them effectively, writers must use them appropriately with respect to their tone, the audience they are writing for, and the purpose of their written work. As a writer, you must master the use of modal verbs as they are instrumental in conveying the author's intended meaning and to effectively communicate your ideas and stance.
