A word order parameter that has been prominent in generative grammar is the order of frequency adverbs and the verb in a transitive sentence. Here we limit ourselves to adverbs that translate ‘often’ (or ‘usually’, ‘mostly’, ‘a lot’, ‘many times’, ‘all the time’, ‘always’). In the values, the order of the subject is ignored, and we only consider full-NP direct objects (not pronominal direct objects). Moreover, we only consider the position of the main verb, ignoring any auxiliary verbs.
By adverb we mean any fixed expression for frequency that is not clearly an argument noun phrase or a verb (phrase). Thus, we include not only single word expressions like often and always, but also fixed phrasal expressions like all the time. However, freely created phrasal expressions (e.g. with high frequency) do not count as adverbs.
