Dyma’r llythrennau sy’n treiglo’n drwynol:
===Treigladau trwynol yn yr ieithoedd Celtaidd ===
 
Mae'r daflentabl ymahwn yn dangos gweithrediadau treigladau trwynolmeddal yn yr ieithoedd Celtaidd. Oherwydd bod llythyraeth unigol gan bob iaith ei horgraff ei hun, cafoddmae'r gyd-enwautreigladau wedi eu rhoitrefnu arnyntyn amôl eu trefnuseiniau. Mae hyn yn ei gwneud yn hawddachhaws cymharu yr ieithoedd. Er enghraifft, mae '''çh''' Manaweg yn hafalgyfartal â '''t''' (''meindwffain'') yn yr ieithoedd Gaelaidd eraill.
 
Mae'r gellcell lwyd yn dangos bod dim treiglad trwynolmeddal yn yr iaith honno am y llythyren honno.
