In phonetics terms the difference between approximant and sonorant
is that approximant is a consonant sound made by slightly narrowing the vocal tract, while still allowing a smooth flow of air. Liquids and glides are approximants while sonorant is a speech sound that is produced without turbulent airflow in the vocal tract; the generic term of vowel, approximant, nasal consonant, etc.
