| Diachronically, the rise of consonant gradation in Germanic can be explained by Kluge's law, by which geminates arose from stops followed by a nasal in a stressed syllable. |
| For many words, however, the most common misspelling seems to be to violate conservation of geminates, and write the word with no doubled consonants at all. |
| In Korean, geminates arise from assimilation, and they are distinctive. |
| Some geminates, however, are clearly more morphologically distinct than others are. |
| The combinations of identical phonemes called geminates occur in the phonology to show inter-syllabic relationship. |
| Some spelling variants without geminates might indicate the preservation of the vowel length of the stem. |
