Tiel Burn 1856 OS 6 inch 1st edn.
‘Flood, torrent’, OIr tuile. That Tiel was formerly *Tul is clearly seen from early forms of Invertiel KGH, which lies near its mouth, such as Invertul, Invertuyl, Inuertule (thirteenth century), with the unrounded vowel not appearing until the sixteenth century (e.g. Inuertele, Inverteile). For full details see Invertiel KGH below. It also forms the second element of the parish-name Auchtertool ATL, in which it has retained the older vowel-quality.
In its upper reaches the burn is now called the Bottom Burn (OS Pathf. 385), and forms part of the boundary between ABO and ATL, then (as the Tiel) between ATL and KGH. In its lower reaches it forms the boundary between KGH and KDT.
