IMPLICATIONAL LAWS - Coggle Diagram

- - - - Pharyngeal fricatives ([ħ] - [ʕ], the “throaty” sounds used in Arabic) , voiceless vowels, clicks (tsk, tsk!) and voiced stops ([ã], [ḁ], [x], [s], [d], [ð]) are less common in languagues.
        
        The more common counterpart of a voiceless pharyngeal fricative is a voiceless velar fricative.
        
        For each less common sound in the inventory, there tends to be a more common sound in the inventory which is just like the less common sound except for one or two phonetic features.
    - - Voiceless stops ([a], [k] or [s], [t], [d] or [z]) are more common in languages.
        
        Alveolar fricatives are more common than pharyngeal fricatives because the tip of the tongue is more agile than the back of the tongue.
- - - - More common sounds also have a wider distribution within a language, that is, they are used in more phonetic environments than less common sounds.
  - - - For example, when a child says [dɪs] instead of [ðɪs], it is because he has not yet acquired [ð], but he does know [d], which is the most common counter art of [ð].
