When one syllable is followed by another syllable, the pronunciation of the second syllable can occur in one of four ways.
If the syllable which ends in a consonant is followed by a syllable which starts with a vowel, the syllable-final consonant of the preceding syllable must be carried over to the next syllable-initial position. We call this case "Liaison".
If the preceding syllable ends in a consonant and the following syllable has a syllable-initial consonant, the situation is quite different. When the following syllable starts with a consonant, the pronunciation of the consonant can occur in three ways, either "glottalization, nasalization, or lateralization".
