I am having a problem identifying the type of verb tense 'became' falls under.
Sentence: I became aware of the fact that I was surrounded by people of my own nationality.
At first I thought it was Past Simple but when I started to look into it further I got confused because it is an irregular verb. I need to be able to explain this to my students as they are learning the different tenses but do not understand how and when to use the word.
I hope that someone could help me please.
