Translation:I have a tall and skinny boy.
Said the slave merchant...
Or in ordinary setting: Said the dad.
So is the s in slab pronounced like a z because of the consonant cluster at the beginning of the word?
Nope, the audio is wrong, it's a /s/.
Here is masculin(inalt si slab not feminin inalte si slabe)
Is it not subțire in stead of slab?
