Wikipedia page on difference between Vedic and classical Sanskrt mentions that...
"Vedic Sanskrit had a voiceless bilabial fricative (/ɸ/, called upadhmānīya) and a voiceless velar fricative (/x/, called jihvāmūlīya)—which used to occur when the breath visarga (अः) appeared before voiceless labial and velar consonants respectively. Both of them were lost in Classical Sanskrit to give way to the simple visarga."
Can somebody point out some words from Vedic Sanskrt which had these sounds /ɸ/ and /x/ in them? /ɸ/ is approximately same as English f, as in fan. /x/ is normal خ sound of Arabic/Farsi.
