Get One's Head Around
phrasal verb
To understand something difficult or complex; OR to accept or come to terms with a surprising situation
The teacher explained the new math formula three times, but most students still couldn’t get their heads around it. They sat there staring at the board with confused faces, whispering to each other and hoping someone would explain it in simpler words.
This meaning is about trying to understand something that feels complicated or confusing. Imagine studying a new programming language and staring at the screen for hours because you just can’t get your head around how the code works. This is getting your head around something — mentally processing it until it clicks. You might say “I can’t get my head around this grammar rule,” or a student could say they finally got their head around calculus after weeks of studying. Or picture reading a contract full of legal language and struggling to get your head around what it actually means. The word suggests mental effort and patience.
Vivid example: When she first started her accounting job, she couldn’t get her head around the company’s complicated tax system. But after a month of practice and asking lots of questions, everything finally started making sense.
This meaning is about emotionally accepting something shocking or unexpected. Imagine your best friend suddenly telling you they’re moving to another country next week — you just can’t get your head around it because it happened so fast. This is struggling to get your head around a situation — not about intelligence, but about emotional processing. You might say “I still can’t get my head around the fact that he quit,” or someone could say they need time to get their head around a sudden breakup. Or picture a family learning they won the lottery and sitting in silence because nobody can get their head around the news. The word carries disbelief and the need for time. ✏️ This phrase is almost always used with “can’t” or “couldn’t” — people rarely say “I got my head around it easily.” It’s built for those moments when something is genuinely hard to process.
Vivid example: His father had always been healthy, so when the doctor delivered the bad news, he simply couldn’t get his head around it. He sat in the waiting room for an hour, replaying the words over and over, unable to believe what he’d just heard.

– British vs American — “get my head around” is strongly British; Americans almost always say “wrap my head around.” Both mean exactly the same thing. If you’re speaking with Americans, use “wrap”; with British people, use “get”

– The possessive changes with the subject — “I can’t get MY head around it,” “she can’t get HER head around it,” “they can’t get THEIR heads around it.” The possessive must match the person — this is a common learner mistake
