Thanks, I will say, to Rasmussen's law, that PIE /*s/ yields in
Albanian, except /gj/, also /j/, we are now able to explain many
Albanian words from PIE forms: *senti/sonti > janë `(they) are',
<jatër/jetër> or prefixed form <t-jatër/t-jetër> `other' (cf.
ambël/ëmbël < *omlos `bitter' and <tambël> `sour milk') from PIE *sm.-
tero (*s>j, m. >a and er > -ër). To not mention here demonstrative
pronouns <ai/ajo> `he/she', <ata/ato> `they', etc.
I like to point out that relation between Greek <heteros> `other' and
Albanian <jatër> was noticed very long ago by Dhimiter Kamarda,
accepted also by Pedersen, but with no convinient explanation.
