Approximants are speech sounds that involve the articulators approaching each other but not narrowly enough, nor with enough articulatory precision, to create turbulent airflow. Therefore, approximants fall between fricatives, which produce a turbulent airstream, and vowels, which produce no turbulence. This class is composed of sounds like (as in ) and semivowels like and (as in ' and ', respectively), as well as lateral approximants like (as in '''').

==Terminology== Before Peter Ladefoged coined the term approximant in the 1960s, the terms frictionless continuant and semivowel were used to refer to non-lateral approximants.
