Final answer:
Synonyms should be used to replace an awkward or overly used word in a presentation to keep the language fresh and understandable. While transitional words are crucial for flow, they are not typically replacements for synonyms. Always choose words that are suitable for the audience and context of your presentation.
Step-by-step explanation:
To replace an awkward word, or one that is used too frequently in your presentation, synonyms should be used. Synonyms are words or phrases that have the same or nearly the same meaning as another word or phrase in the same language. Using synonyms helps to enhance the variety in your language and keeps your presentation fresh and engaging for your audience.
Transitional words and phrases, such as 'further,' 'consequently,' 'meanwhile,' and 'therefore,' are also important as they show the connections between ideas, but they are not used to replace overused or awkward words. Instead, transitions help to give your writing a proper flow and guide your readers through your arguments or descriptions smoothly.
When dealing with a word you're not sure about, it's always good practice to replace it with a synonym you are confident using. This strategy not only strengthens the clarity of your presentation but also displays a keen understanding of vocabulary. Remember that your choice of words should always be appropriate for your text and your audience.
