Origin of It

  • From Middle English, from Old English hit, from Proto-Germanic *hit (“this, this one”), from Proto-Indo-European *ḱe-, *ḱey- (“this, here”). Cognate with West Frisian it (“it”), Low German it (“it”), Dutch het (“it”), German es (“it”). More at he.

    From Wiktionary

  • A representation of the pronunciation of hit by a speaker whose dialect lacks the voiceless glottal fricative or transition (IPA: [h]). Not to be confused with hit, which is a dialectal variant of the pronoun it.

    From Wiktionary

  • Middle English from Old English hit ko- in Indo-European roots
