Common mistake:
Learners sometimes say *"simultaneous to"* instead of *"simultaneous with"*. In most cases, use: *"X is simultaneous with Y"*. Learners also confuse *simultaneous* with *spontaneous*; *simultaneous* is about time (things happening together), while *spontaneous* is about something happening suddenly or without planning.
