ticking (n.)
"cloth covering (usually of strong cotton or linen) for mattresses or pillows," 1640s, from tyke (modern tick) with the same meaning (mid-14c.), probably from Middle Dutch tike, from a West Germanic borrowing of Latin theca "case," from Greek thēkē "a case, box, cover, sheath," from suffixed form of PIE root *dhe- "to set, put."
