Hedna ew mar dha . That is so good.
Hedna ew da genam. I like that.

Re boos ew ev rag an estyllen. It’s too heavy for the shelf.
Rag hedna, ma’n lever poos ma war an leur.

Cas ew genam an lever na. I hate that book.

Drog ew, pur dhrog. It’s bad, very bad.

Old rhyme, giving advice:
Na wrewgh eva re, Don’t drink too much,
Bes evow’ rag ’gas sehes, But drink for your thirst,
Ha hedna, moy po le, And that, more or less,
’Vedn gwitha corf en ’ehes. Will keep a body in health.
