Verbs have a central role in language processing but simultaneously verbs tend to represent a greater cognitive load on processing than nouns. An important characteristic of the verb lexicon is that in all languages, a small number of verbs appear to be dominant in terms of frequency. The most frequent verbs in an individual language are referred to as basic verbs.Among the basic verbs in any language, there is a set of nuclear verbs which tend to have the same basic meaning in all languages (a universaltendency). In addition, there are some basic verbs that have alanguage-specific meaning. The paper summarizes research based on a computerized learner corpus with data from projects concerned with Swedish as a second language of children and adults. The primary data were recordings of oral production carried out individually with learners at several points in time. One of the major findings was that L2 learners tended to favour nuclear verbs which wereboth over used (in terms of frequency of occurrence) and over extended (withrespect to their semantic coverage). Language-specific meanings tended to be weakly represented at early stages of L2 acquisition
