Arabic has had a great influence on other languages, especially in vocabulary. The influence of Arabic has been most profound in those countries visited by Islam or Islamic power.
Arabic loanwords have made into many languages as diverse as Amharic, Albanian, Armenian, Azerbaijani, Balochi, Bengali, Berber, Bosnian, Bulgarian, Catalan, Chaldean, Chechen, Croatian, Dagestani, English, French, Georgian, German, Greek, Gujarati, Hausa, Hebrew, Hindi, Indonesian, Italian, Kazakh, Kurdish, Kutchi, Kyrgyz, Macedonian, Malaysian, Odia, Pashto, Persian, Portuguese, Punjabi, Romanian, Serbian, Sicilian, Spanish, Sindhi, Somali, Swahili, Tagalog, Tigrinya, Turkish, Turkmen, Urdu, Uyghur, Uzbek, Visayan and Wolof as well as other languages in countries where these languages are spoken. Other languages such as Maltese and Nubi derive from Arabic, rather than merely borrowing vocabulary. Spanish has one of the largest Arabic-influenced vocabularies of any European language, around 8 percent, due to Arab rule mainly in the Southern Iberia from 711 until 1492 known as Al-Andalus, however Spain's re-Christianization and resulting loss of contact with Arabic culture has led to a significant shift in both meaning and pronunciation of Spanish words of Arabic etymology.
The terms borrowed range from religious terminology (like Berber taẓallit, "prayer" < salat), academic terms (like Persian manteq, "logic"), to everyday conjunctions (like Hindi/Urdu lekin, "but"). Most Berber varieties (such as Kabyle), along with Swahili, borrow numbers from Arabic. Most religious terms used by Muslims around the world are direct borrowings from Arabic, such as ṣalāt, 'prayer' and imām, 'prayer leader'. In languages not directly in contact with the Arab world, Arabic loanwords are often mediated by other languages rather than being transferred directly from Arabic; for example many older Arabic loanwords in Hausa were borrowed from Kanuri.
Outside the Muslim world, there are more limited borrowings from Arabic, usually to denote vegetables and other articles in commerce, such as "aubergine", "alcohol" and also some other terms like "admiral". Among European languages, these mostly were transmitted through Spanish and Turkish.
Bengali
The Bengali language, spoken by the Muslim-majority Bengalis, has gained Arabic vocabulary both directly, as the language of Islam and its literature, but also indirectly as a consequence of Arabic-influenced Persian being an official language in Bengal for over 500 years. During the late medieval period, a number of Bengali Muslim writers also wrote Bengali using the Arabic script. In the coastal Chittagonian dialect, the Arabic influence is magnified with researchers considering half of the dialect's lexicon to be of Arabic origin.
Berber languages
Most Berber languages have a high percentage of borrowing and influence from the Arabic language, as well as from other languages. For example, Arabic loanwords represent 35% to 46% of the total vocabulary of the Kabyle language, and represent 51.7% of the total vocabulary of Tarifit. Almost all Berber languages took from Arabic the pharyngeal fricatives /ʕ/ and /ħ/, the (nongeminated) uvular stop /q/, and the voiceless pharyngealized consonant /ṣ/.
The influence of Arabic, the process of spirantization, and the absence of labialization have caused the consonant systems of Berber languages to differ significantly by region. Berber languages found north of, and in the northern half of, the Sahara have greater influence from Arabic, including that of loaned phonemes, than those in more southern regions, like Tuareg. Many Berber languages have lost use of their original numerals due to the influence of Arabic, such as Tarifit which lost all except one.
Catalan/Valencian
Arabic has notably influenced the Catalan language, and especially the southern dialects (including the Valencian ones). Due to almost eight centuries of Arabic presence in the Iberian Peninsula (Al-Andalus), hundreds of words from many fields (including Arabic inventions) have been adapted into Catalan; among many are séquia ("irrigation ditch"), nòria ("waterwheel, noria"), algorfa ("loft"), magatzem ("warehouse"), alfàbia ("earthenware jar"), barnús ("bathrobe"), aladroc ("anchovy"), dacsa ("corn"), safanòria ("carrot"), carxofa ("artichoke"), albergínia ("aubergine"), xirivia ("parsnip"), alfals ("alfalfa"), albercoc ("apricot"), tramús ("lupin"), corfa ("bark, peel"), xara ("thicket"), matalaf/matalàs ("mattress"), alacrà ("scorpion"), fardatxo ("lizard") alfàb(r)ega ("basil"), etc. and expressions such as a la babalà ("randomly, to God's will") and a betzef ("abundance, plenty").
