I best liked the anagrams and RELATED & LADDER. I still do not see how “as if camping” is IN TENTLY – IN TENT or IN TENTS maybe. And thanks for the help in parsing 1d.
Thanks Mudd and Teacow
Nothing too taxing, and good fun. I always enjoy puzzles that don’t require repeated resorting to Wikipedia or Google.
With NEWSPRINT I spent too much time trying to use an anagram of “pristine”, although I was sure it was right. It took a while to convince myself that “strip” and “dismantle” are synonyms. And I was flummoxed by fhe voting system.
I took 2d as a double definition. HERE and ITEM UNDER THE TREE.
For camping, in-tent-ly is a made-up, whimsical adverb, Martyn @1. Got a 🙂 from ginf.
I enjoy novelty/ whimsical clues, so no quibbles, and some very crafty wordplays.
Like GDO@2, I felt STRIP and DISMANTLE had a chink of daylight between them, but I use both/either when working on my old Wankel car engine; and mantle has a “clothing” / robe connotation, so ( back to the whimsy), [DIS MANTLE] = [ DIS ROBE] = STRIP.
I found the clues economical, skilful, with well-put-together surfaces, and quite friendly….so
Here’s mud in your eye, both Teacow & Mudd
Agree with Grant@4 that, in-tent-ly was probably a whimsical offering. I thought of PRESENT as more of a double definition.
The puzzle was a lot of fun though I needed a reset to complete the upper portion where I just wasn’t seeing clearly on my first pass. Can’t think why in retrospect but I did come here to understand ‘cock’ as regulator. I was surprised to see ‘item’ in three separate clues but that’s a minor point which didn’t affect the solve.
For strip /dismantle, I thought of guns (though I don’t speak from experience! ) but my Dad, too, would use both for car engines.
I liked FEVERISH CLEOPATRA best.
Thanks Mudd and Teacow.
Thanks Mudd and Teacow
13ac further to earlier comments: note the question mark on the end of the clue indicating the whimsical definition of IN-TENT-LY.
6dn again further to earlier comments: The meaning of dismantle for removing clothing is in the Shorter Oxford 2010 p 707, but marked as obsolete and 17th century only. Still current is the meaning “Strip (something) of necessary equipment, covering, furniture, or apparatus”.
Thanks, Diane@6, and Pelham@123.
DISMANTLE….
Diane’s dad used it re his car engine; and “to disrobe” , per Mr.B, is valid, but archaic.
It just confirms how very old I am getting.
I only got CLEOPATRA at 8(ac) because I knew her mother.
I liked CAPTAIN and EMERALD. I can’t see a problem with “strip=dismantle” in the engineering context.
ENBoll& @8
Ah yes, I knew her too. I always called her Cleomatra.
