Maybe you mean REALIZE? Yes it is a verb.
The infinitive form is "to realise" (British spelling). It is regular. I realised you realised (singular) he, she or it realised we realised you realised (plural) they realised An example is: I realised that I was in trouble when the boat sank.
He has realised that you are a boring person
No, she realised it was an accident !
Assuming you mean First Bull Run, they both realised that their armies were not ready for operations.
It means he realised he was too "forward" by smiling at you, so is now trying to control himself.
The cast of Never Realised - 1989 includes: Taya Francis as herself
I was about to unlock my car door but then I realised that I lost the keys.Note: If you are in the United States then replace "realised" with "realized".
In 2008
The past tense is realised (British English) or realized (US English)
In England we spell it Realised, with an S not a Z.
