"Mi wnes i ffonio Ceri Lingo."

Translation: I phoned Ceri Lingo.

[RozieToez]

Did the audio mutate Ceri to sound like Geri?

[rmcode]

It sounds like it, but it's an artefact of the text to speech which while being good is not perfect

[OliverMundy]

Am I right in thinking that this construction of the past tense with gwneudd (I hope I have remembered that verb correctly) is a virtually exact parallel to the archaic English construction with 'did' (e.g. 'I did see' as an alternative for 'I saw')?

[rmcode]

Yes, and 'gwneud' is used very extensively in spoken Welsh, in particular in the North to form the past and future tenses.

[Julianbark6]

And you'll also notice a tendency among Welsh speakers to say things like "I did see" inplace of "I saw".

[Wayne-Poulton]

Why is 'I have phoned Ceri Lingo ' incorrect?

[mizinamo]

That's present perfect -- which in Welsh would be Dw i wedi ffonio Ceri Lingo.

[RuthAnders56748]

Two things. 1. Since this is not a negative statement or a question, why is the g dropped? Also, what do the numbers mean before each persons comment?

[mizinamo]

Since this is not a negative statement or a question, why is the g dropped?

Because of the pre-verbal particle mi, which causes soft mutation.
