reflexive and ergative verbs:-

1 The reflexive pronouns (see pronouns) are:

Singular:	myself; yourself; himself; herself; itself
Plural:	ourselves; yourselves; themselves

We use a reflexive pronoun after a transitive verb (see Clauses, Sentences and Phrases) when the direct object is the same as the subject of the verb:

I am teaching myself to play the piano.
Be careful with that knife. You might cut yourself.

These are the verbs most often found with reflexive pronouns:
 

• cut
• dry
• enjoy
• hurt
• introduce
• kill
• prepare
• teach

Some verbs change their meaning slightly when they have a reflexive pronoun as direct object:

• amuse
• apply
• busy
• content
• behave
• blame
• distance
• express
• find
• help
• see

I wish the children would behave themselves.	=	I wish the children would behave well.
He found himself lying by the side of the road.	=	He was surprised when he realised that he was at the side of the road.

He busied himself in the kitchen.	=	He worked busily in the kitchen.
I had to content myself with a few Euros.	=	I had to be satisfied with a few Euros.

The verb enjoy always has an object:

We all enjoyed the party.
I really enjoyed my lunch.

If enjoy has no other object, we use a reflexive pronoun:

They all enjoyed  They all enjoyed themselves.
I really enjoyed  I really enjoyed myself.

NOTE: We do not use a reflexive pronoun after verbs which describe things people usually do for themselves:

He washed in cold water.
He always shaved before going out in the evening.
Michael dressed and got ready for the party.

We only use reflexives with these verbs for emphasis:

He dressed himself in spite of his injuries.
She’s old enough to wash herself.
