little did I know
Look back on a moment when you were unaware of an important, often surprising development that became clear later.
nisam ni slutio / slutila; malo sam tada znao / znala

Memory scene
Freeze the story just before the reveal: your past self sees a tiny blank space, while the narrator now sees the whole twist.
How it sounds
LIT-l did eye NOH
Stress little and know; did supports the dramatic inversion.
Build the sentence
Little did + subject + base verb, often followed by that / how / what
Use it
Little did I know that the person beside me would become my business partner.
The narrator reveals later significance that was invisible at the earlier moment.
We thought the detour was a nuisance; little did we know, the main road had already flooded.
The phrase creates a dramatic reversal between what was believed then and what is known now.
Watch out
Because fronted little is negative, use inversion and the base verb: Little did I know, not Little I knew or Little did I knew. It is marked storytelling language, not merely a neutral way to say I didn’t know.
Nearby language
The closest everyday alternative, without the same narrative suspense or inversion.
More formal and factual; it does not by itself promise a later reveal.
The present-tense version describes what other people remain unaware of now.
