Language software applications encounter new words, e.g., acronyms, technical terminology, loan words, names or compounds of such words. To add new words to a lexicon,  we need to indicate their inflectional paradigm. In this article, we evaluate a lexicon-based meth-od augmented with data from a corpus or the internet for selecting the inflectional paradigm of new words in Finnish. As an entry genera-tor often produces numerous suggestions, it is important that the best suggestions be among the first few, otherwise it may become more efficient to create the entries by hand. By gen-erating paradigm suggestions with an entry guesser and then further generating key word forms for the suggested paradigms, we were able to find support for the paradigms in a corpus. Our method has 79-83 % precision and 86-88 % recall, i.e. an F-score of 83-86 %, i.e. the first correctly generated entry is on the av-erage found as the first or the second candi-date.
