I did wonder if 24dn is a reference to the old “Something old, something new, something borrowed, something blue.” The something borrowed would be on loan.
I think 28a is supposed to be ENGAGÉ.
I thought the best explanation for 2d was drawer=DR and lengthwise=ALONG with ‘cut’ presumably indicating that ‘drawer’ was abbreviated but only necessary for the surface reading. I thought the clue would have been better if ‘(not good)’ was removed and ‘cut’ indicated that ALONG should be cut short.
I agree with Dormouse about TROUSSEAU.
I also agree with Matthew about 28a (but I’ve forgotten how to include accents). For 3d, DR=DRAWER is in Chambers; I think it’s banking terminology, referring to chequers.
Sorry, that should be cheques.
Dormouse @1 – you are right. Under the entry Something Old in Wikipedia I find this:
The usual effect on the bride of the Evil Eye is to render her barren, and this is obviated by wearing “something borrowed”, which should properly be the undergarment of some woman who has been blessed with children: the clothes communicate fertility to the bride.
Definitely on the easy side for Azed, when it did eventually appear on the Guardian’s website. The number of question marks I have at the end, very few in this case, is usually a pretty good indicator of difficulty.
At 34a perhaps the Ge is referring to the Greek goddess of earth Ge (alternative spelling of Gaea).
Yes ernie, I think you have a better explanation for ge than I do.
