Position of tout = everything

Question

Hi all.  there are 3 examples of using tout meaning everything, and the position of the words varies each time, can someone please explain why/ the difference, thanks

Bonjour Lana,
Depending on its function, tout (when meaning everything) will be positioned differently in a sentence:

Tout est parfait = Everything is perfect
Tout a été annulé = Everything got cancelled

-> subject

J'oublie tout = I forget everything
J'oublais tout = I used to forget everything

J'ai tout oublié = I forgot everything
J'avais tout oublié = I had forgotten everything

-> direct object - its position varies depending on the tense used (Simple tenses such as Le Présent or L'Imparfait / Compound tenses such as Le Passé Composé or Le Plus-que-Parfait).
 
I hope this is helpful.
Bonne journée !
