| I 1 (ī) pron. Used to refer to oneself as speaker or writer. n. pl. I's The self; the ego. [Middle English, from Old English ic; see eg in Indo-European roots.] Usage Note: The question of when to use nominative forms of the personal pronouns (for example, I, she, they) and when to use objective forms (for example, me, her, them) has always created controversy among grammarians and uncertainty among speakers and writers. There is no problem when the pronoun stands alone with a single verb or preposition: every native speaker says I (not me) read the book; They told him (not he); The company bought a computer for us (not we); and so forth. But the decision is more problematic in other environments. · When pronouns are joined with other nouns or pronouns by and or or, there is a widespread tendency to use the objective form even when the phrase is the subject of the sentence: Tom and her are not speaking to each other. This usage is natural in colloquial speech, but the nominative forms should be used in formal speech and writing: John and she (not her) will be giving the talk. · When pronouns joined by a conjunction occur as the object of a preposition such as between, according to, or like, many people use the nominative form where the traditional grammatical rule would require the objective; they say between you and I rather than between you and me, and so forth. Many critics have seen this construction as originating in a hypercorrection, whereby speakers who have been taught to say It is I instead of It is me come further to assume that correctness also requires between you and I in place of between you and me. This explanation of the tendency cannot be the whole story, inasmuch as the phrase between you and I occurs in Shakespeare, centuries before the prescriptive rules requiring It is I and the like were formulated. But the between you and I construction is nonetheless widely regarded as a marker of grammatical ignorance and is best avoided. · In other contexts the traditional insistence that the nominative form be used is more difficult to defend. The objective form sounds most natural when the pronoun is not grammatically related to an accompanying verb or preposition. Thus, in response to the question "Who cut down the cherry tree?" we more colloquially say "Me," even though some grammarians have argued that I must be correct here by analogy to the form "I did"; and few speakers would accept that the sentence What, me worry? is improved if it is changed to What, I worry? The prescriptive insistence that the nominative be used in such a construction is grammatically questionable and is apt to lead to almost comical pedantries. · There is also a widespread tendency to use the objective form when a pronoun is used as a subject together with a noun in apposition, as in Us engineers were left without technical support. In formal speech or writing the nominative we would be preferable here. But when the pronoun itself appears in apposition to a subject noun phrase, the use of the nominative form may sound pedantic in a sentence such as The remaining members of the admissions committee, namely we, will have to meet next week. A writer who is uncomfortable about using the objective us here would be best advised to rewrite the sentence to avoid the difficulty. See Usage Notes at be, but, we. |

"The reason for writing I is ... the orthographic habit in the middle ages of using a 'long i' (that is, j or I) whenever the letter was isolated or formed the last letter of a group; the numeral 'one' was written j or I (and three iij, etc.), just as much as the pronoun." [Otto Jespersen, "Growth and Structure of the English Language," p.233]The form ich or ik, especially before vowels, lingered in northern England until c.1400 and survived in southern dialects until 18c. The dot on the "small" letter -i- began to appear in 11c. L. manuscripts, to distinguish the letter from the stroke of another letter (such as -m- or -n-). Originally a diacritic, it was reduced to a dot with the introduction of Roman type fonts. The basic word for "I" in Japanese is watakushi, but it is not much used. Words that boys usually use are boku (polite) or ore (OH-ray), a rougher word, which can be rude depending on the situation. Girls usually use atashi (a feminine-sounding word) or the neutral watashi, but a tomboy might use boku like boys do.
