"Could you speak slowly, please?"

Translation: Allet ti siarad yn araf, plîs?

[Sarah-Cheung]

So it doesn't matter to mix "ti" and "chi" up in the same sentence? For example to use "ti" in the first part of a sentence, and then use "os gwelwch chi'n dda" at the end, or vice versa.

[EllisVaughan]

I almost certainly do it (not sure if it is strictly speaking correct but people definitely do it).

[Sarah-Cheung]

Cool~

[Llyfrgellydd]

I did that now and it was marked wrong. :)

[Nethromaniac]

Os gwelwch chi'n/yn dda instead of "plîs" is getting marked wrong on this one

[ibisc]

If you are starting the sentence with a ti-form (allet/fedret ti...?) then you should use the ti-form of 'please' - os gweli di'n dda (or plîs).

All versions of 'gallech chi' were marked wrong for me on this.

It is a question, so it must have a soft mutation -Allech chi...?

[ninevoltheart]

Oops, that was silly of me! I'll pay more attention next time :p

I am a bit confused with " gallet ti " and "allet ti" Is "allet" the soft mutation of "gallet"? If so, in sentence like this one, "allet" is the first word of the sentence, what's causing it to be soften? Or are these two interchangeable? Thanks in advance !

It is.

If so, in sentence like this one, "allet" is the first word of the sentence, what's causing it to be soften?

The ghost of a question particle that is (I believe) no longer used but has left its leniting influence behind :). (I think the particle is/was a. It's still used in Cornish - W Allet ti...? = C A allses ta ...?)

Or are these two interchangeable?

Not sure about this. I believe they are in positive statements, where you can use mi + lenition, fe + lenition, just lenition (after the "ghost" of a mi or fe), or no lenition, but I don't know whether this is true for questions or whether those do need the lenition.

Thank you for the ghost story lol

Fedret is completely brand new to me, it wasn't introduced. I only guessed the right sentence through process of elimination. How odd.
