Each of the 5 theme answers has the last letter of the last word in a phrase doubled and an A is added to create a totally different phrase, clued with wit. With no intention to offend anyone, since I live in a community that is 60% 1st generation Italians, the rhythm of the new word created sounds to me like an Italian speaking English. For me that enhanced the whimsy and enjoyment of the puzzle. David is more than 5 years into his second career in making puzzles, and has made some really great ones; read his INTERVIEW. While I loved the theme, the word count, blocks and fill are mostly a Thursday feel for me. The sparkle was present in ALOMAR, AMULET, C-NOTES, MOGULS, SERENE, UGANDA, VOODOO, LIBERIA, COMANECI, and KICKED IN without too many 3/4 letter fill and only a few omnipresent ones like ATE and ANTE. Let's see how it all sounded to you.
