136 CORNISH ROCK-NAMES, &c., AND IRISH WORDS. 
CoFFIN. _Old open workings. There is the Irish word cabhan (pronounced 
cavaun), Which means a hollow. There is also the word cobhan (pro- 
nounced cowan), a coffer. 
Costran. To trace or find tin. Probably similar to cos (pronounced cuss) 
foot, or the bottom of anything, and stan, tin. As we now say “ go to 
the bottom of it,” if we want to search out anything. 
Cuarr; Quare; QuarEy. Pryce considers this to be the Cornish for a 
quarry of stones, a corruption from quares, joints. There are somewhat 
similar terms in Ireland; as a Connaughtman will say “there is no 
quarry” in a rock mass without joints—Coir, plural cora, is an old 
term used by the famous Irish mason, Goban Saor.—Cuir, the verb, is, 
to place, to put, to build. Cairthe (pronounced caire) is a heap of 
stones or anything in layers. The French for quarry is carriere, from 
carrer to square, which equals the Latin quadrare. 
Diso. The Lord of the soil’s part of the ore raised—evidently similar to 
duais, a right, a due, a prince, a lord. 
Dizzvz; DyHa. Probably from a similar root as that of the word duais. 
Doar; Oar. Probably similar to odhar (pronounced ower), virgin soil. 
According to Pryce, oar or ore is derived from doar, earth. Dubh-ar is 
black earth or soil. 
Dou. Similar to the Irish dail, a divide, a share. 
Durns; Dorn. Wooden frames to support weak ground in an adit. Probably 
similar to dion, to protect; asthe durns protect the miners from danger 
while passing through the adit. Or it might have a connection with 
the Irish dorn, a fist. 
Evan; Hetvan. Similar to e/ or oil, rock, and ban, white; the b changing 
into v on account of its position. The name evidently is derived from 
the white smooth weathering peculiar to Elvanyte and all other felsitic 
rocks, more especially when compared with the dark rough weathering 
of granite masses. - 
Frucan; Fuoocan. Similar to fliuchan, a soft oozy, or miry moist substance, 
which is derived from the verb fliuch, to wet, to moisten. 
Foegr. A forge or blowing house for smelting tin; Irish fogaoth, a small 
wind, a draught. 
Forcquz; Forx. See Bottom in fork. 
Gav. Now used in Cornwall to signify a wedge; this however seems to be 
a corruption of the word, as in Ireland gad means a withe, or rope, of 
osiers or similar materials, used by smiths and quarrymen as handles 
for the wedge, to preserve their hands from being struck. Many of the 
ancient stone and bronze implements seem to have had ‘‘gads” for 
handles. 
Gau; Cau; Kat. A whitish yellowish color, like that of cream.
