In English, phonological double consonants only occur across morphological boundaries, for example, in affixation (e.g. in unnatural, innumerous). There are two possibilities for the phonetic realization of these morphological geminates: Either the phonological double is realized with a longer duration than a phonological singleton (gemination), or it is of the same duration as a singleton consonant (degemination).
