From Middle English I ( also ik, ich), from Old English ih ( also ic, iċċ (“I”)), from Proto-Germanic *ik, *ek (“I”), from Proto-Indo-European *éǵh₂ (“I”). Cognate with Scots I, ik, A (“I”), Saterland Frisian iek (“I”), West Frisian ik (“I”), Dutch ik (“I”), Low German ik (“I”), German ich (“I”), Bavarian i (“I”), Danish and Norwegian Bokmål jeg (“I”), Norwegian Nynorsk eg (“I”), Swedish jag (“I”), Icelandic ég, eg (“I”), Latin ego (“I”), Ancient Greek ἐγώ (egṓ, “I”), Russian я (ja, “I”), Lithuanian aš (“I”). See also English ich.

I (first person singular subject personal pronoun, objective me, possessive my, possessive pronoun mine, reflexive myself)

1. The speaker or writer, referred to as the grammatical subject, of a sentence.
   • 1590, Edmund Spenser, The Faerie Queene, III.ii:

     It ill beseemes a knight of gentle sort, / Such as ye haue him boasted, to beguile / A simple mayd, and worke so haynous tort, / In shame of knighthood, as I largely can report.

2. (nonstandard, hypercorrection) The speaker or writer, referred to as the grammatical object, of a sentence.

• The word I is always capitalised in written English. Other forms of the pronoun, such as me and my, follow regular English capitalisation rules.
• I is the subject (nominative) form, as opposed to me, which is the objective (accusative and dative) form. Me is also used emphatically, like French moi. In some cases there are differing views about which is preferred. For example, the traditional rule followed by some speakers is to use I as the complement of the copula (It is I), but it is now more usual to choose me in this context (It's me).
• When used in lists, it is often thought more polite to refer to self last. Thus it is more natural to say John and I than I and John. In such lists, we generally use the same case form which we would choose if there were only one pronoun; since we say I am happy, we say John and I are happy, but we say Jenny saw me, so we say Jenny saw John and me. However, colloquially one might hear John and me are happy, which is traditionally seen as a case error. As a hypercorrected reaction to this, one can occasionally hear phrases like Jenny saw John and I.
