Contextual aids to word meanings

Type and examples

 

The following are ways to define words within a text. These forms of definition of words and terms can also be used to teach students to use context as clues to meaning while reading content-area texts. These are also useful as strategies for defining words in writing without isolating words from their context, thus focusing students on associating words with their related concepts.
