dönemde

Dönemde is a Turkish grammatical form that functions as the locative case of the noun dönem, meaning period or term. It translates roughly to “in the period” or “during the term” in English and is used to situate an event or state in time.

Formation and usage: The locative suffix in Turkish is -de or -da, chosen by vowel harmony. Since the final vowel of dönem is front (e), the suffix appears as -de, producing dönemde. This form is used within sentences to indicate the time frame during which something occurs or is true. It is not a standalone noun but a temporal marker that accompanies the noun it derives from or combines with in context.

Typical usage patterns include phrases like bu dönemde (in this period, during this term) and dönemdeki (the period’s or within the period, when used with additional suffixes to form larger phrases). It is commonly found in academic, historical, economic, and political discourse.

Examples:

- Bu dönemde teknolojide hızlı ilerlemeler kaydedildi. (During this period, rapid advances in technology were recorded.)

- Dönemdeki değişiklikler kamuoyunda tartışıldı. (The changes during the period were discussed publicly.)

Relation to other terms: Dönemde is related to the base noun dönem and to other temporal expressions such as süre (time span) and zaman dilimi (time interval). It belongs to a broader category of Turkish locative expressions that situate actions in time rather than space.
