In English there are a variety of causal adjunct phrases such as because of, as a result of, on account of and in spite of. It was reported recently that a new structure because X is thriving in colloquial registers including conversations and blogs. The complement X is not only restricted to nominals but also includes other lexical categories such as adjectives, adverbs and even verbs. This article delves into the history of this usage and its reasoning, and conducts a survey on other causal adjuncts to determine whether the same kind of innovation is observed with other adjunct phrases. The survey shows that the new usage started from NP complements and has been extended to include complements of other lexical categories, and that the new usage attested in because X is also observed with in case X. The truncation of the final preposition is verified with all the adjunct phrases in the survey, but the category of the complement is basically restricted to nominals in the case of other phrases. We will look into the factors segregating the two groups of adjuncts, namely because/in case X, and other causal adjuncts.
