+##### Gemination
+
+Gemination is found in several languages including Italian and Japanese.
+It is also present in the suprasegmental phonology between words such as
+"lamppost" and "evenness".
+
+Some linguists use the [long](#length) suprasegmental for geminate consonants.
+The eSpeak NG convention is to use consonant length for [phonation](#phonation)
+when consonant length is distinct without gemination occurring.
+
+The way gemination is represented in eSpeak NG is to duplicate the phonemes,
+with the first phoneme using the `unx` feature. For example, n̚.n for a
+geminated n. This describes how with the `stp` and `nas` consonants, the
+mouth remains closed (`unx`) for the first of the geminated consonants.
