Typical Tuesday puzzle. Mostly easy clues with straightforward wordplays.
Enjoyable all the same because of the nice surface stories. Liked ELECTRIC, OSTENSIBLE, NAIL, CHEST, ALL THE SAME, AIR. Not to mention the well hidden AVOCADO PEAR. Thank you GURNEY.

I read 15d as ALL THE TIME.
Coby @1, of course. Forgive the typo. Have corrected it since.
Thanks Bhavan and Gurney. As you say, not too taxing but I did have to google a list of Russian authors to get TURGENEV (I had the ‘enev’ ending so guessed Russian but am a bit lacking in knowledge of 19th century authors generally…)
I thought just ‘writer’ for 30a was unacceptably loose. It effectively means one of any nationality from any time in history – quite a selection! Given that turgid is not the most obvious synonym for bombastic and there is no indication that we need the middle three letters of Geneva, not just the E, I thought it a poor clue.
We were not looking for any synonym for “bombastic”, but one that ends in “-id”, which makes it easier.
Thanks Gurney and Bhavan
A really nice crossword that was over too quickly.
Finished with CURFEW, SLANDER and the very clever SEXIST. I had heard of Ivan TURGENEV and have been going to read his “Fathers and Sons” for ages … must do it !!
