Lemma Searching

Note: While TLG is a database of Greek texts, all of the author names and titles of works are in Latin.

What does searching by lemma mean? - "A Lemmatized Search [aka, search by lemma] allows the user to enter a lemma, i.e. the dictionary form of a word, and retrieve all inflected forms linked to this lemma and present in the TLG corpus" (TLG help page). In other words, a lemma is a base word, headword, or 'dictionary form' of a given word. An example in English would be the lemma "go" which would include the different forms of "go," "goes," "going," "went," and "gone." By searching by lemma, one can find all the forms tied to a given lemma and then limit search results to a more exact word form if desired. "The advantage of using lemmatized searches is that the user can retrieve in one search a large number of forms that might otherwise require multiple string searches."

  • To do a lemma search, select the "Lemma"  button, rather than the "Word Index" button (on the "Text Search" screen). 
  • After clicking on the Greek keyboard icon, type in the Greek word you would like to search for. 
  • Then, click "Go." The search results will appear. 

 

  • Afterwards, you can filter your results (selecting only the inflected forms you want to see) using the "selection" column on the left side of the screen.
  • NOTE: You can adjust the lines of context from the Greek text that appear, by using the lines of context box above the results.

If you wish to locate a printed copy of the Greek text where your word occurs, click on the red title of the work.​
