I have got your back
Today’s idiom is one that I have heard quite often recently. It is the expression to have got someone’s back. Used informally, this English phrase means ❛to support, look out for or protect someone❜. For example:
Child: I am afraid. I don’t know what I am going to do with my life.
Mother: Don’t worry. I have got your back.
When the mother says she has got her child’s back, she is saying that, ❛if anything goes wrong, she will be there to help and support her child❜. Often, instead of I have got your back, people also say I got your back.
You can learn a lot of new English idioms in the following short video of US President Barack Obama making a speech on a 2011 visit to Australia. In this speech, he intentionally uses some informal Australian idioms such as to give it a burl (= to try/attempt something), a chinwag (an informal talk) or earbashing (angry criticism), just to name a few. In reference to Australian-American relations, the American President also says we have got each other’s backs, which means ❛we always look out for and support each other❜.
