Adisyonel

Adisyonel is a Turkish adjective meaning "additional" or "supplementary." It is used in formal, technical, and administrative language to denote items, amounts, or charges that are not part of the base total. The word is a loanword from French additionnel, itself from Latin additio, and has entered Turkish through European linguistic influence.

Common contexts for adisyonel include budgeting and accounting (adisyonel giderler, adisyonel maliyetler), fees (adisyonel ücret), and services (adisyonel hizmetler). In contractual or legal texts, it may describe appended clauses or circumstances that raise the amount or scope beyond the initial terms. In hospitality or retail, adisyonel charges or items refer to add-ons beyond the core order; however, everyday Turkish often prefers ilave or ek for such additions.

Usage notes: adisyonel tends to be more formal and technical, so it is common in written reports, contracts, and official communication. In less formal contexts, speakers may opt for synonyms such as ilave or ek. The related noun adisyon can refer to a bill or itemized receipt in some Turkish-speaking settings, with adisyonel modifying charges or features associated with that bill.
