Answer: Library. "I hold countless voices that never speak": This refers to the vast number of books in a library. Each book contains the "voice" (ideas, stories, knowledge) of its author, but the physical book itself is silent. "countless journeys that never move": Books describe "journeys" (adventures, travelogues, fictional quests), but the books remain stationary on the shelves. The reader takes the journey through their imagination. "and ask for quiet to share them all": Libraries traditionally require a quiet atmosphere so that patrons can read, study, and focus on the material within the books without distraction.

Answer: Infinity. It’s the process of counting: start at 1, then keep adding 1—2, 3, 4, and so on—without stopping. The total “grows” because the number increases, but it “never ends” because there’s no largest number; you can always add one more. Infinity is not a specific number, but rather a concept representing something without any bound or end, perfectly matching the description in the riddle.

Answer: A Mailbox. A “mailbox” has “letters,” but they’re mail, not alphabet characters. It also has a “flag,” the small lever you raise to signal outgoing mail, even though it isn’t a pole with a flag. So both clues fit a mailbox through wordplay.

Answer: Ice Cream.  Here's a breakdown of the clues: "I am sweet and cold": This directly describes the primary qualities of ice cream. "with a stick to hold": This specifies a common way ice cream is served as a convenient handheld treat, often with a wooden stick. "a treat on a hot day, worth more than gold": This highlights the refreshing and highly desirable nature of ice cream when the weather is hot.
