- | Let's try finding collocations of a word such as //bread//. We select EEBO as the corpus we wish to work with and then use a basic query type. After clicking on the search button, concordance lines will appear. //Bread//, a key word, is always located in the middle of the line (higlighted in pink). We then click on the **collocations** button located in the upper menu and select **custom** from the dropdown menu. | + | Let's try finding collocations of a word such as //bread//. We select |

- | Don't worry about the grammatical words and punctuation marks in the first positions. Function words such as prepositions and articles are the most common words in any language and therefore they frequently co-occur with //bread//. As the EEBO corpus is not lemmatized, it is not possible to restrict the search to adjectives and nouns only. | + | Don't worry about the grammatical words and punctuation marks in the first positions.
