Hello all. After a slow start I've made good progress with only 5 left to go. However I must have gone wrong as I seem to be in a death loop with nothing fitting. Unclued 11d I am pretty sure is J-; unclued 13 d seems to be F-; unclued 19d seems to be the proper name M-. But now I cannot fill 27a 'OED founder new viral flu infected(9)'. 29a and 36a remain mysteries. Can anyone offer a hint for 27a or the unclued 13d so I might break the logjam please?
Vetuste, thanks also for the hints. Yes I have the prefixes. Unfortunately now stuck again - this time on 29a. I have ARM?A but this seems to be a blind alley. Thanks in advance if you can set me straight!
Thank you bathtub...not a word I'm familiar with and it not being in Chambers led me to dismiss it at an earlier stage. Didn't the Spectator always used to say if an answer didn't appear in the BRB? Anyway, all done now, thank you all for your help!
