lemmar utilizes tokenization and dictionary lookup for lemmatization of text. Lemmatization is defined as

"grouping together the inflected forms of a word so they can be analysed as a single item" (wikipedia)

While dictionary lookup of tokens is not a true morphological analysis, this style of lemma replacement is fast and typically still robust for many applications.
