In carpentry and construction, the word member refers to any individual piece or part that makes up a larger, assembled structure. And the Times has Collins as its reference, which has “a component part of a building or construction”. So I think it’s okay.
Thanks for explaining 44a, I also couldn't understand it.
15a Slowly notice a US soldier close to Oman's capital (6).
Adagio? Can't quite parse it.
Notice = ad, a = a, US soldier = GI, Oman's capital = o. So what's the 'close to' doing?
