From Sanskrit दा (dā), meaning "to give." This root is cognate with Latin *dare* and Greek *didōmi* ("to give"), all tracing back to Proto-Indo-European *deh₃-* ("to give"). The Hindi infinitive suffix -ना (-nā) was added in the Old Hindi period, giving देना (denā).

In Indian culture, giving (देना) carries deep social and spiritual weight. The concept of *daan* (दान, charitable giving) is a cornerstone of Hindu, Buddhist, and Jain ethics — giving to others is seen as an act of merit. In everyday speech, देना also functions as a causative helper verb (e.g., *करने देना* — "to let [someone] do"), making it doubly essential for intermediate learners to master.
