Beyond lumping and splitting
Unlike synchronic linguists, who can ask their consultants for additional data and examples, historical linguists are, for the most part, stuck with the data we have. Only rarely are we able to add to the corpus of available texts, or find additional examples of a rare combination of phonemes. The problems of historical linguistics are thus inherently probabilistic: we must constantly decide wh...

A diagnosis of COPD based on spirometry alone should therefore trigger further investigation ...
