Continuing in the jughead direction from the previous entry, I've been looking into the Sanskrit word for 'head', mûrdhan, which also appears in the Indian grammarian term, mûrdhanya 'cerebral, or retroflex, articulation'. This series of consonants, mainly stops, are pronounced with the tip of the tongue curled up and back inside the mouth touching the roof of the mouth. (Just imagine Peter Sellars doing his stage Indian accent pronouncing any word with a 't' or a 'd' in it.) When transliterating Sanskrit words, these retroflex consonants have dots underneath them. Anyway, the reconstructed Indo-European root for mûrdhan is quite strange:
*m^elh_xdho-.
It only appears in a few words in Avestan, Sanskrit, Greek, and Old English. [Gk blothros 'tall', OE molda 'top of the head; elevation'.]
