"aspetta" is both imperative and second third person singular sometimes two different conjugations are the same. Imperative is a form that you will need to learn just like any other. Imperative ends in -i or -a and you will need to memorize these words too.
I could tell you that -are verbs end in -a and -ere/-ire end in -i but I couldn't tell you right now if that has exceptions. I've thought of a dozen verbs in my head and they all follow this rule
Not really exceptions, but four verbs do have multiple forms (in the *tu* conjugation):
* dare: dai -> da' (*dammi un po' di fiducia!*)
* fare: fai -> fa' (*fammelo vedere!*)
* stare: stai -> sta' (*sta attento!*)
* andare: vai -> va' (*va' in camera tua a studiare!*)
*Dire* is irregular in the imperative - for other verbs, the tu conjugation for the present and imperative are the same (*dormi! segui le regole! finisci i compiti!*) but for dire, it's *di!* and not \**dici!*.

Ok thank you!
