Understanding Prefixes

The video tutorial introduces prefixes and their role in expanding vocabulary. It explains how prefixes like 'un', 'dis', 're', and 'pre' modify base words to create new meanings. The prefix 'un' can mean 'not' or 'the opposite of', depending on whether it is attached to an adjective or a verb. Similarly, 'dis' functions like 'un', indicating 'not' or 'opposite'. The prefix 're' signifies 'again', while 'pre' means 'before'. The tutorial also warns about prefix lookalikes, such as 'distant' and 'uncle', which are not true prefixes.
