From Old Swedish tighl, from Old Norse tigl, from Proto-Germanic *tigulǭ. Same as Icelandic tigl, Danish tegel, Old English tigele, English tile, Middle Low German tegel, German Ziegel, Latin tegula, a form of tegere (“to cover”) (a roof with tiles), relating to Swedish tak (“roof”) and täcka (“to cover”). Thus, it was first used for roof tiles, later for wall bricks. Brick building was introduced in Scandinavia with the cathedral in Roskilde, Denmark (started in the 1170s), and later led to the "Brick Gothic" (Backsteingothik) in Scandinavia and Northern Germany.
