päevasel

Päevasel is an Estonian term used to denote something related to daylight or daytime. It is formed from the noun päev (day) with the suffix -sel, which in Estonian marks a temporal or locational reference. In practice, päevasel by itself is rarely used as the main word; it most often occurs within compound phrases such as päevasel ajal (during the day) or päevasel valgusel (in daylight). The sense is complementary to öisel, which relates to night and nighttime contexts.

Usage and scope: In meteorology, photography, and urban planning, päevasel indicates that a condition or measurement pertains to daytime light conditions. In literature, it may be employed for stylistic emphasis on daylight. The term is more common in formal or technical writing than in everyday speech, where speakers typically use standard phrases like "päeval" or "päevasel ajal" without treating päevasel as a standalone lexical item.

See also: daytime, daylight, öö, öisel ajal.

Notes: As a derivational form, päevasel illustrates how Estonian forms variations of day-related concepts to specify time of day in phrases rather than as a separate headword.
