In a live sentence
A single word almost never appears alone in conversation. A sentence shows where it fits and what stands next to it.
- أي يوم؟айй йаум؟Which day?
Nearby words: basic words
Yes, no, good, bad, very. The small change of a language — and no sentence assembles without it.
- نعمнаамyesShort and firm. In conversation an Arab often answers not with yes but by repeating the verb: "do you like it?" — "I like it"
- لاляnoThe same word negates the present tense: laa aʿrif — I do not know. The past is negated by ma — two particles for two tenses
- جيدджейидfineThe standard answer in full: ana bikhayr, shukran — I am well, thank you — or a short jayyid. From the root "to be good"
- سيئсаййиʾbadThe doubled y is held long and the word is cut off by a hamza at the end: say-yi-ʾ. The partner of jayyid, and just as common in an answer
- ممتازмумтазexcellentFrom the root "to outdo". A stronger answer to how are you than jayyid: it means it cannot be better
- يمكنюмкинit is possibleAn impersonal "it is possible": it has no subject at all. "Can I pay by card?" is built on exactly this word
- وваandIt is written attached to the next word: wa sticks like a prefix. Khubz wa jibna — bread and cheese
- لكنлякинbutIt opens the second half of the sentence. With a long a on the end — laakinna — it sounds stronger, with a press
- كيلوغرامкилограамkilogramAt the market they say it short — kilo. Half is nisf kilo, and the weigher measures exactly so, with no grams involved
- نصفнисфhalf"Half an hour" is nisf as-saaʿa, and an Arab divides time into halves more readily than quarters. A short word, but the s here is soft, interdental

How not to forget this word
Reading a word and remembering it are different jobs. A day later, little survives of a single reading — and that is not bad memory, that is how memory works.
- This has been tested on foreign words too. The difference shows up most when you test yourself a few days later rather than straight away.checked many timesKim & Webb, 2022, Language Learning 72(2) · 48 experiments, 3,411 participants, 98 comparisons.
