Erinnern vs. sich erinnern
The German words erinnern and sich erinnern both relate to the concept of memory, but they are not interchangeable. The key difference lies in whether someone is being reminded by an external source or is actively remembering something themselves.
Erinnern
A2This is a transitive verb that means to remind. It requires a subject (the person or thing doing the reminding) and a direct object (the person being reminded). The structure is: Someone/Something reminds someone (Akkusativ) of something (an + Akkusativ).

(Can you please remind me of the dentist appointment?)

(Your story reminds me of an old movie.)
Sich erinnern
A2This is a reflexive verb that means to remember or to recall. The action of remembering is performed by the subject on themselves. It is almost always used with the preposition an followed by the thing being remembered in the accusative case. The structure is: Someone remembers something (sich an + Akkusativ).

(I can no longer remember his name.)

Summary
In essence, the difference is simple: erinnern means to remind and involves an external trigger, where one person or thing makes another person remember. Sich erinnern means to remember and is an internal, reflexive action where a person actively recalls a memory from their own mind.
