The answer to the crossword clue "microscopic android, 7 letters" is NANOBOT.
Here's why:
- Microscopic: Nanobots are incredibly small, often measured in nanometers.
- Android: While not a traditional android in the humanoid sense, nanobots are often described as tiny robotic machines, functioning autonomously, thus fitting the broader definition of "android" in this context as an artificial entity.
- 7 Letters: Nanobot perfectly fits the letter count requirement.
This is a clever clue playing on the dual meanings of "android." While usually referring to a human-like robot, in this case, it refers to a self-operating miniature machine.
