"It is twenty minutes past twelve."
Translation:Mae hi'n ugain munud wedi deuddeg.
when is "ugain" allowed? when is "hugain" allowed? It's not a mutation, yet I keep getting it wrong.
The normal spelling is 'ugain' however after the preposition 'ar' if changes to 'hugain'.
In time this applies to
Ugain munud wedi...... and Ugain munud i...** (Twenty past and twenty to)
Pum munud ar hugain wedi...... and Pum munud ar hugain i (literally 'Five minutes on twenty past' and 'Five minutes on twenty to'......)
Hope that clarifies it.
