labialization (countable and uncountable, plural labializations)

(phonology) A secondary articulatory feature of usually consonants that involves the contraction or rounding of the lips (labia) during pronunciation.
- 1935, Bernard Bloch, American Speech:
  These labialized stops are of course nothing but positionally determined allophones of the [t] and the [k] phoneme, and their labialization is non-distinctive
- 2013, Bülent Gül, Ferruh Ağca, Faruk Gökçe, editors, Bengü Bitig. Dursun Yıldırım Armağanı‎^[1], page 551:
  The second question concerns the reasons for the labialization of this suffix in [1.3] - in the case of artukluk one immediately thinks of an assimilation (*u - ı > u - u)
