Hindi

The seventh and final group of consonants -- श, ष, स, ह -- is the fricative consonants ( Fricative consonants). As an aerospace engineer, fricatives are easy for me to understand. Fricatives are formed by forcing the air from your lungs into a tight channel and causing turbulence in the air flow; it's like placing a model in a wind tunnel.

श
śa, /ɕ,ʃ/

ष
ṣa, /ʂ/

The sixth group of consonants -- य, र, ल, व -- is the approximant consonants ( Approximant consonants). The approximants sound similar to their corresponding English consonants, as shown in the transliterations below. Approximants are special because they resemble vowels -- a sort of middle sound between vowels and consonants.

य
ya, /j/

र
ra, /r/

ब
la, /l/

ल
va, /ʋ/
