A2 Norwegian GrammarTemporal Prepositions

Master Norwegian prepositions for expressing time: 'i' (in/for), 'på' (on/in), 'om' (in - future), 'siden' (since), and 'til' (until). Learn which preposition to use with different time expressions and avoid common mistakes made by English speakers.

1Basic Time Prepositions: i, på, om

Norwegian uses different prepositions for time than English. 'I' is used for months, years, and periods. 'På' is used for days of the week and specific times of day. 'Om' indicates future time ('in X hours/days'). These distinctions are crucial for natural Norwegian.

i = for (duration)

2Since, For, Until: siden, i, til

'Siden' means 'since' and refers to a point in time when something started. 'I' expresses duration ('for'). 'Til' means 'until' and indicates the end point. 'Fra...til' creates a time span. These prepositions often combine with perfect tense.

3Time of Day Expressions

Norwegian has specific patterns for times of day. 'Om morgenen/kvelden/natten' describes general times. 'På dagtid/nattestid' means during day/night. 'I morges/i går kveld' are fixed expressions for this morning/yesterday evening.

4Common Mistakes and Special Cases

English speakers often confuse 'i' and 'for' when expressing duration, or misuse 'om' and 'i' for future time. Also note that 'om' + day of week means 'by' in some contexts. Fixed expressions must be memorized as they don't follow regular patterns.
