Laryngeals

[Peter &/or Graham]

Re the note on laryngeals and -u, what about laryngeals and i (outside the
Sanskrit reflex of syllabic laryngeals)?
    1.  Sanskrit forms such as de- from da: (before y- in some forms)
    2.  The number of laryngeal roots which appear with -i forms in some
languages:  (s)terH(i), (s)perH(i), treH(i) and a number of others.
    (3.   Does the Hittite -i- in dai have an explanation within Hittite?)

Is there a connection, or is this a chimaera?
