Mae Geirfa'r Glowr yn cyfeirio at 'peitiswr' a 'paitsh':

 

peitsiwr - gweithiwr mewn rhai o weithfeydd glo Y Rhos a ddefnyddiai'r paitsh...math o focs tun ...a dynnid ar hyd y llawr ac o dan y glo a orweddai yng nghyffiniai'r wyneb...

 

ond does dim cofnod o ferfenw (patsio).

Mae 'patshys' glo yn ddigon cyfarwydd i fi o ardal Merthyr, ac roedd yna ddyn o'r enw Dai Patsh ym mhentre Heolgerrig pan o'n i'n fach, ond dwy ddim wedi clywed na gweld 'patsio' - a dyna fyddech chi'n disgwyl ei glywed mae'n debyg. Er bod GPC yn cyfeirio at patsh/pats fel 'ardal a weithir i gael mwyn brig', does dim enghraifft yno o'r berfenw mewn cyd-destun glofaol.

 

Oes gan rywun gopi o Geirfa'r Glöwr, rhag ofn bod cofnod yn honno?

Sori, fi eto. Yr un pwnc:

 

Originally coal exposed on the surface was mined by patching, but once the surface coal was exhausted miners tunnelled into the hillside in a process called drift mining.

Found close to the surface they were worked by digging shallow holes. You can see lots of these old workings (called patching) along the Heads of the Valleys. 

 

Fyddai 'clytio' yn gwneud am 'patching'??

 

Diolch
