Yes, Natalia! Kotonda alone is also a verb in the infinitive form meaning (to get full or to satiate) but it can also be an adjective or an adverb. For example if I say EZA YA KOTONDA = It's full. LIBENGA NANGAI EZA YA KOTONDA NA MBONGO. = My pocket is full of cash or money. I hope that helped clear your confusion. Good question though as always! 😊
Plz remove the laughing 'pop-eye' / zombie at the end of each of your lessons, it is irritating / embarrassing especially if listening with a friend who doesn't understand yo deep interest in Lingala language. Otherwise I enjoy your lessons very much, botondi mingi ndeko nangai. I'm learning Lingala from Zimbabwe
