+
+Previously, we discussed that vowels in unstressed syllables might be reduced to a *schwa* ə ([2.1.5-ə](2.1.5-ə)). In natural speech, even the *schwa* ə can be further weakened to a very light ɤ. For example, take the common word *reasonable*. The dictionary may mark it as ˈriːzənəbəl, but in real-life conversations, you often hear it pronounced as ˈriːzɤnəbəl. This means the syllable "*so*" sounds more like ɤ rather than zə.
