On the top of their tongues

This is another beauty from The New York Times. Here’s the quote: “What exactly would a President Harris do? That question was not on the top of the tongues of many delegates this week.” 

This is a mashup of “on the tip of (one’s) tongue” (almost able to be recalled) and “off the top of (one’s) head” (from memory or without much consideration). “On the top of (one’s) list” might also be in the mix given the context. “Top of mind” was suggested by Yvonne Stam as part of the mix, and certainly seems so as it fits with the story. Another salute to Barry Eigen for spotting this one and sending it in.
