How would you explain “on her tongue” in the context? The cathedral was packed with solemn children, farmers, and old women on tree-trunk legs. Some worked their way through the Stations of the Cross, orbiting around the crowd's periphery as deliberately as planets. A long line of townspeople waited to receive communion, but Salome walked to the head of the line, accepting the host on her tongue as if this were a bakery line and she had plenty of other errands. How would you explain “on her tongue” in “accepting the host on her tongue”? Thanks!
