"Dw i eisiau tegannau."

Translation: I want toys.

[spenerish]

What would be the singular of "tegannau"?

[SanzoneDuolingo]

Toy-Tegan
Toys-Teganau

Thank you!

Is -au the only way to form plural words? Or is -au more likely to be applied to a word that ends with n e.g oren, tegan?

[SanzoneDuolingo]

Not with every word.For example,"Dogs" would translate to "cŵn" and "Birds" would translate to "adar"."Au",yes,is mostly applied to words ending with N.

I'm confused. Is there one or two "n" in the word "toys"?
