Your own definition of 넓습니다 includes "spacious" so my answer should be accepted.

Remember though that both of the bottom consonants are pronounced when a vowel follows them.
Therefore '넓어' is pronounced as 'nolbo'. 붉다 (pukta, ㄹ silent) -> 붉어 (pulgo); etc
in romanisation it is, 'neorb' but it sounds more like 'narb' with the 'b' being light, or with a light 'm' sound. the 'n' also sounds nasally.
