Answer :
reflective pronouns are pronouns that are used for the object of a verb when it refers to the same noun as the subject of that verb. in english, these end with "self" or "selves." you don't use a reflective pronoun when the object and subject of a verb are different
a sentence could turn grammatically incorrect when using a reflexive pronoun wrong
incorrect use: "Please contact to Milo or myself if you have any questions."
correct use: "They shook themself awake."
hope this makes sense lolol
