Learn something so well that you can remember it exactly.
The actress sat backstage with the script in her hands. She had spent three weeks trying to memorize every single line, repeating them over and over until she could say them perfectly without looking at the page.
This meaning is about deliberately learning something until you know it by heart. Imagine a student sitting at her desk the night before an exam, reading the same list of vocabulary words again and again until she can memorize every single one without checking. This is memorizing — storing information in your mind through repetition. You might memorize a phone number by repeating it several times, or someone could memorize a poem for a school performance. Or picture a waiter who memorizes the entire menu on his first day so he can answer questions confidently. The word carries a sense of effort and practice. ✏️ Unlike “remember,” memorize always involves intentional effort — you choose to learn it, it doesn’t just stay in your mind naturally.
Vivid example: The little boy wanted to impress his grandfather on his birthday. He spent a whole week trying to memorize a short poem in Turkish, practicing it every night before bed until he could recite it without a single mistake.
Examples from the street:

“Don’t just memorize the answers — make sure you actually understand them.” → Don’t simply store the responses in your head — be sure you truly grasp the meaning behind them

✔ Native usage tips
– “Memorize” vs “memorise” — spelling difference only — Americans write “memorize” with a Z; British English uses “memorise” with an S. The pronunciation and meaning are identical. Both are correct — just be consistent with whichever system you follow
– “Memorize” vs “remember” — these are not the same thing. “Memorize” means you deliberately learn something so you can recall it exactly. “Remember” is broader — you might remember a holiday without ever trying to memorize the details. You memorize on purpose; you remember naturally
– “Memorize” often has a slightly negative feel in education — modern teaching philosophy tends to view memorization as shallow learning. You’ll often hear “don’t just memorize — understand.” This doesn’t mean memorizing is bad, but it’s frequently contrasted with deeper thinking
– “Learn by heart” is the warmer, friendlier alternative — while “memorize” can sound mechanical and academic, “learn by heart” feels more personal and emotional. “She memorized the poem” sounds like a task; “she learned the poem by heart” sounds like she truly absorbed it
– “Have something memorized” is very natural in speech — native speakers say “I’ve got it memorized” or “I have the password memorized” far more often than “I memorized it.” The state of having learned it matters more than the act of learning it
– The noun form is “memorization” not “memorizing” — while both work, “memorization” is the standard noun: “rote memorization,” “memorization techniques.” In casual speech, “memorizing” as a gerund is fine: “I’m tired of all this memorizing”
✔ Similar expressions / words
– Learn by heart → warmer and more emotional than “memorize”; implies deeper personal connection to the material; “learn the vows by heart” sounds romantic while “memorize the vows” sounds like homework
– Commit to memory → more formal and deliberate; used in professional, military, or academic contexts; “commit the procedure to memory” sounds official while “memorize the procedure” is more everyday
– Cram → informal and negative; means to memorize large amounts of information quickly, usually right before an exam; “I crammed all night” implies rushed, panicked studying with no real understanding
