maddelerinde

Maddelerde is a Turkish locative form meaning “in the substances” or “within substances.” It is the plural form of madde (substance, matter) combined with the locative suffix -de, following the plural suffix -ler. The result maddelerde is used to indicate location or occurrence inside multiple substances or materials.

Its use is common in scientific and technical writing, including chemistry, materials science, geology, pharmacology, and related fields, as well as in general language when referring to substances in plural. The construction allows speakers to discuss properties, reactions, distributions, or changes that occur within various substances collectively rather than in a single substance.

Examples:

- Kimyasal reaksiyonlar maddelerde hızlı bir ivmeyle ilerler.

- Çözeltide maddelerdeki konsantrasyon değişirse tepkime hızı etkilenir.
