What is the name of a sound shift law under which the Proto-Germanic vowel "e" changes to the English "i", e.g.
*fehtaną (fechten) -> fight;
*rehtaz (recht) -> right
As mentioned in this other answer:
In Old English, front vowels […] got raised before
/xt/. This is why vowels before English ght are generally higher than before German cht: see also recht~right, etc.
