Origin
From Middle English hat, from Old English hætt, from Proto-Germanic *hattuz (“hat”), perhaps from a late PIE root Proto-Indo-European *kedʰ- (“to guard, cover, care for, protect”) or wanderwort. Cognate with North Frisian and Danish hat (“hat”), Norwegian Bokmål, Norwegian Nynorsk, and Swedish hatt (“hat”), Icelandic hattur (“hat”), Finnish hattu (“hat”), Latin cassis (“helmet”), Lithuanian kudas (“bird's crest or tuft”), Avestan 𐬑𐬀𐬊𐬛𐬀 (xaoda, “hat”), Persian خود (xud, “helmet”), Welsh cadw (“to provide for, ensure”). Compare also hood. Verb sense 4 derives from a common English Wikipedia template used to collapse disruptive discussions, {{Hidden archive top}}, abbreviated as {{hat}}.
