Reflexive pronouns, like 'myself' or 'herself,' show when the object of a sentence is also the subject of a sentence. Examples include 'I saw myself in the mirror' or 'We bought ourselves a snack at the farmer's market.'

Sometimes we use reflexive pronouns like 'myself' and 'ourselves' for emphasis in a sentence, like, 'If you won't help me, then I'll do it myself!' KA's Grammar Fellow, David, explains this usage.
