jäännöslopuke

Noun

 * 1)  a virtual phoneme at the end of a word that causes gemination

Usage notes
In the Finnish language, (sandhi-induced) gemination is the phenomenon in which the first consonant of the following word becomes geminated. If the next word begins with a vowel, there is a double glottal stop between the words. The tendency of a word to cause gemination in the following word, which is what jäännöslopuke as a term describes, is sometimes marked with [ˣ] or [(ʔ)] in IPA and the actual gemination of a consonant may be marked with [ː] or by doubling the consonant (see purje, vene, purjevene).
 * tule come + tänne  here + autolla  by car →
