"Dewi Lingo went to Wales."

Translation: Aeth Dewi Lingo i Gymru.

[HaroldWonh]

Why is it "Aeth" and not "Gaeth"?

[ibisc]

See the section notes in PastTense2, earlier in the course, for the short-form simple past conjugations of mynd, dod, gwneud, cael.

• aeth comes from mynd (going, to go)
• gaeth (caeth) comes from cael (getting, to get, being allowed to, ...)

[OwenPr1]

Aeth is the past tense of mynd and gaeth is the past tense of cael.
Also wnaeth is the past tense of gwneud.

[Nate_J]

Correct, but wnaeth is specifically the softly mutated form of the past tense of gwneud. Without any mutation it's gwnaeth

Why not 'Mi wnes Dewi Lingo fynd i Gymru.'?

[ibisc]

Because Mi wnes i means 'I did':

• [Mi wnes i/Gwnes i] fynd - I went
• [Es i/Mi es i] - I went

'He did' is Gwnaeth e/o, and so:

• [Mi wnaeth o/Wnaeth o/Gwnaeth o] fynd - He went
• [Mi aeth o/Aeth o] - He went
• [Mi wnaeth/Wnaeth/Gwnaeth] Dewi fynd - Dewi went
• [Mi aeth/Aeth] Dewi - Dewi went

Have a look back over the notes for the various sections on 'Past...' for more details.

(And in any of those examples we can use e in place of o. You may sometimes come across Fe in place of Mi in front of the verb, too.)

Thanks! That helps.
