Living Room
Sitting Room
noun
A room that comes alive in intervals is your living room. You don't spend all your time in there, so it can only be alive sometimes. This word is usually used for western style living rooms by the way, so don't mistake it for a traditional Japanese one.
The readings for this word are both kun'yomi readings. You've learned both of these readings by now so you should be able to read this on your own.
父は居間でテレビを観ています。
Dad is watching TV in the living room.
