I write these posts to help people get started with cryptic crosswords. If there is something here you do not understand ask a question; there are probably others wondering the same thing.
Thanks Sleuth and PeeDee
Appreciate the blog today, as it fixed up some sloppy parsing that I had at 18a (where I hadn’t broken the word play down), 28a (where I only looked out for ETON) and 13d (where I thought that it was just the first three letters of Chinese … and wondered what the island was doing there! derrrhhh).
Didn’t know of the ‘service tree’ until today. The rest of the puzzle was pretty straightforward with GORMLESS the last one in.
I would hate to see anyone “scraping” an Amati-caress, attack even but scrape??!!
Everything was going fine till I put in ‘snowsuit’ (sort of fits for the wordplay) for 5a, making 5d and 6d impossible. OEUVRE and the ‘service, say’ also fooled me so I ended up taking much longer than I should have.
GORMLESS was my favourite. I felt like it as I was struggling in my frustration to finish this.
Thanks to Sleuth and PeeDee
Well I solved it. But cold not parse 9 ac. Why is tree synonymous with service? Seems to beat PeeDee and me too. That needed 2dn (simultaneous last ones in) before it got entered. Is there a better parsing?
Two typos above. Could not cold. 11 ac not 9 ac. Apologies
Service is a “ tree very like the Rowan “ definition 2 in Chambers. My mind rests in peace.
