|Notes:||This stem is often irregular and maybe was irregular already
in IE Proto-language times. Another opinion is that the stem was just affected by the IE
vowel interchange, which made ei > i > e'.
English does not have any relatives to the stem, it can be found only in borrowings from Latin: initial < initium (a beginning), itinerate < itineris (of a way)
French has the related future and the conditional present of aller (to go) - j'irai (I shall go), and also the verb subir (to undergo).
Also every civilized language, we believe, have such words as transit and ambition, which are derived from the same stem.
