,,I started to cry"in indirect speech?
Man müsste wissen, wie der Satz eingeleitet ist. Wer sagt das (zu wem)?
I said / I told him/her/them that I had started to cry.
He/She told me/us that he/she had started to cry.
Wenn das einleitende Verb im Past steht wird das "Simple Past" der direkten Rede normalerweise zu "Past Perfect".
She/He had started to cry.
Glaube ich zumindest.
He/she said that he/she started to cry.
