I think. Therefore I am
The word I is the single most repeated word in the English language and as the initial character of introspection, idealistic, indulgent, illuminating, id, illustrious, individualistic, and identity, it's not surprising that I people exhibit such strong self-esteem. This kind of confidence is commonly seen in the traditional meanings of names like Imogene (image), Irving (handsome and fair), Inez (pure), Ismael (God listens), and Ilyssa (rational).
Typically, I people are more intuitive than practical, and more ego-driven than most, and with the exception of the letter R, I people are more likely to become doctors and famous entertainers than any other initial letter. They suffer nonetheless from the same problem as the other ego-related vowel, the A; their self-assurance is often mistaken for conceit and egotism. This explains why surveys show that people almost never associate I names with either feminine warmth or robust masculinity.
But when it functions as a terminating letter, the I has an entirely different effect. There is no comparison, for example, from the arrogant pronunciation of the I in Ivan, to the feminine pronunciation of the I in Tammi, for whenever words end with a high pitched letter (I or Y), they invariably remind us of the reassurance that a mother gives to a child – mercy, mommy, kitty, doggy, femininity, etc.
