Connectives (Discourse Markers)

Sentence coherence is integral to sentence effectiveness. Appropriate connectives should be used to connect words, phrases and clauses in a sentence. In order to achieve coherence, technical writers and speakers use several linking devices or connectives.

CONNECTIVES (Discourse Markers)

 

Sentence coherence is integral to sentence effectiveness. Appropriate connectives should be used to connect words, phrases and clauses in a sentence. In order to achieve coherence, technical writers and speakers use several linking devices or connectives. There are two types of linking devices, overt and covert. Overt devices are direct and explicitly stated while covert devices are indirect and implicit. Covert devices include techniques such as repetition of the key word, the use of articles (a, an, the), pronominal forms (he,she, it, they, and so on), and the use of synonyms. However, technical communication largely uses overt linking devices or connectives to indicate the logical progression of ideas in oral discourse or writing.

 

Following are some examples, in which connectives (bolded) have been used:

 

        When an object is placed on one side or the other of a converging lens and beyond the focal plane, an image is formed on the opposite side.

 

        If the object is moved closer to the primary focal plane, the image will be formed farther away from the secondary focal plane and will be larger.

 

        Land pollution is due to solid wasters.

 

        Fresh water is a renewable source, but its distribution is uneven.

 

        Asbestosis is caused by asbestos, which is used in making ceilings.

 

These connectives include subordinators and coordinators. They can also be classified according to their functions. The following table presents the usage of discourse markers:

 



I. Read the following paragraphs and fill in the blanks with appropriate connectives.

 

I. When Hydrogen gas escapes from a cylinder into the air, no change is visible. However, if the escaping hydrogen is directed at finely divided platinum, it is observed that the platinum glows and soon ignites the hydrogen. In the absence of platinum the H2O2 reaction is too slow to observe. In contact with platinum, hydrogen reacts with oxygen from the air to form water. As they react, the give off energy, which heats the platinum. As the platinum gets hotter, it heats the hydrogen and hydrogen with oxygen becomes self-sustaining.

 

II. Join the following pairs of sentences, using the discourse markers given in the brackets against each pair.

 

1. My father earns plenty of money. He hates spending money on luxurious living. (inspiteof)
