I have learned some of the same words:
Blanket - manta (my friend said, "What are you trying to say"?
)
Sink - fregadero (my friend says this is a wash board, not a sink)
Bathroom sink - lavabo (This was a free-standing sink, not one with a counter top or double sink. Can I use this word to mean both?)
What about stove and refrigerator? I've learned:
Stove - Cocina (showed a stove in a home)
Oven - Horna (showed a large brick oven used in a pizzeria)
Refrigerator - Frigorífico (my Mexican friends don't like this word)
Thanks!
