bel
"Bel" in Catalan means "bleat," the sound made by a sheep or goat.
Here, 'bel' refers to the specific sound made by a lamb, used as a noun.
El bel del xai va ser suau i tranquil.
The bleating of the lamb was soft and calm.
In this case, 'bel' is again a noun, describing the sound sheep make, highlighted within a rural setting.
Vaig escoltar el bel a la granja i sabia que era de l'ovella.
I heard the bleating at the farm and knew it was from the sheep.
Once more, 'bel' acts as a noun for the sound made by the sheep, used in the context of shepherding.
