You already know this.

Literally 'O God' in Arabic — pure direct address. In Hebrew slang it's a permission slip, a hurry-up, a let's-go. The same יא you say in 'yallah balagan' is the classical Arabic vocative particle.

From Arabic ṣabāba — a kind of yearning, lovesick fondness. The romance got sanded off; now it just means 'sweet.'

'Sweeter, sweetest' — Arabic comparative of حلو 'sweet'. Israeli use is the same vibe: 'this is the sweetest.'

From Arabic biʾsa — 'wretched, miserable.' One of the few imported words for the specifically Israeli flavor of disappointment.

In classical Arabic kayf means 'how?' or, as a noun, a state of pleasant feeling. The pleasant-feeling sense came into Hebrew.

Literally 'two healths' — said after a meal, an achievement, a strong workout. The dual ending -ein is pure Arabic.

Passive participle of basaṭa, 'to spread out, to make easy.' Mabsūṭ = the one whose mood has been spread out flat. A relaxed, satisfied state.

Spoken Arabic for 'straight ahead, directly.' Imported into Hebrew with the directness intact.

Same three letters: ר-א-ש in Hebrew, ر-أ-س in Arabic. Different vowels, identical meaning, identical position in your skull.

Two letters, identical in both languages, identical sound.

Eye and spring of water — both languages keep both senses. The metaphor is universal: water rises out of the ground the way tears rise out of you.

Same root: א-ז-ן in Hebrew, أ-ذ-ن in Arabic. The Hebrew ז corresponds to the Arabic ذ (dh) — in JA, that ذ is written as ד'.

Same root letters, with the Arabic preserving the final mem the Hebrew dropped. Biblical Hebrew sometimes shows 'פום' too.

Saadia uses قلب where the Hebrew has לב. Arabic kept the initial qaf the Hebrew dropped; the rest is the same skeleton.

ש and ش are the same letter in JA orthography. Same word, same root ש-ע-ר / ش-ع-ر.

Two letters. Same word.

Two letters. Same word. (The Arabic vowels you to umm, the Hebrew vowels you to em.)

Hebrew ח corresponds to Arabic خ here — in JA, that خ is written as כ' (kaf with apostrophe). Saadia never uses the bare word — always 'his brother' (אכ'יה), 'your brother' (אכ'יך), etc.

Hebrew lost the initial alef; Arabic kept it. The biblical Hebrew 'בן' and the Arabic 'ابن' are the same morpheme.

Plural construct, 'sons of' — same in both languages, used constantly in the Tafsir ('Bnei Israel').

Sun in both languages, sister-shaped: shemesh / shams. Hebrew double-shin, Arabic shin + sin.

Different roots — Hebrew chose ירח (related to 'wandering'), Arabic chose قمر. Saadia translates the Hebrew ירח with قمر, the standard Arabic word.

Same word — Hebrew and Arabic both go back to kawkab, with the same letters in the same order.

Pure cognate, both languages. (Modern Arabic prefers بحر — but yamm is the classical word, especially in poetry.)

Hebrew dual ('two heavens'), Arabic singular — but it's the same root ש-מ-י / س-م-و. Both end in a long ā.

Hebrew has the dual ending; Arabic dropped it to māʾ. The skeleton is the same.

Different roots — but Hebrew also has the verb 'nahar' for 'shine,' and the related noun ner ('lamp') reflects the same n-r root Arabic uses for fire.

Identical letters. Identical meaning.

Same root, same animal. The English word 'camel' also comes from this Semitic root — picked up through Greek.

Hebrew ḥamor / Arabic ḥimār. Same animal, identical letters, slightly different vowel pattern.

Hebrew ש and Arabic س map onto each other in this root. Saadia uses سمع where the Hebrew has שמע — same word, same sense.

Identical root in both languages, identical meaning. The Modern Hebrew מכתב (letter) and Arabic مكتب (office, lit. 'place of writing') are cousins from the same family.

Same letters, same act.

Different roots, despite identical meaning. Saadia uses جلس where the Hebrew has ישב — a place where Arabic and Hebrew chose different verbs for the same action.

Same letters, two senses in Arabic: rijl = foot, rajul = man. (The unvowled JA looks identical for both — only context tells you which.) Hebrew kept only the 'foot' sense.

Same three letters, opposite ends of the menu. Classical Semitic ל-ח-ם meant 'food/substance' generally; Hebrew narrowed it to bread, Arabic narrowed it to meat. Bet-leḥem = 'house of bread.' Bayt-laḥm = same town, in Arabic, with the meat reading.

Different specialization of the same Semitic root — Hebrew ended up with 'book/scroll,' Arabic with 'journey.' (The Arabic word for book is كتاب, from the writing root.)
