kɔsi (Until)

1. From ... to
Pair it with Coming From: firi: Mekɔ sukuu firi Dwoada kɔsi Fiada (I go to school from Monday to Friday), firi nnɔn nkron kɔsi nnɔn du (from nine to ten o'clock).

2. Until a time
Twɛn me kɔsi anwummerɛ (Wait for me until evening). Kɔsi nnɛ means up to today.

3. Until something happens: kɔsi sɛ
Before a clause, add sɛ. For an event still to come, the clause uses the future bɛ-: Twɛn kɔsi sɛ mɛba (Wait until I come). In a past story, the clause is past: ... de kɔsii sɛ nsuo no wee (... until the water dried up, Genesis 8:7).

4. Kɔsi changes with the series
In the past, it takes the past like the verbs before it: Yɛtwɛnee no kɔsii anwummerɛ (We waited for him until evening). See Tense Across Serial Verbs. In a negative series it can take the nasal like the other verbs, as in Negatives in Serial Verbs: Merentena ha nkɔsi anwummerɛ (I will not stay here until evening). Before a clause it can also stay positive: wɔanhunu de kɔsii sɛ nsuo bɛfaa wɔn nyinaa (they did not know until the flood came and took them all, Matthew 24:39).

5. De kɔsi, bɛsi and kɔpem
You will often see de before it: de kɔsi wiase awieeɛ (until the end of the world). For up to now, speakers also use bɛsi, from ba (come): ɛfiri afe 1957 bɛsi nnɛ (from 1957 to this day). Kɔpem and kɔpem sɛ mean the same as kɔsi and kɔsi sɛ.

6. Before
Kɔsi sɛ looks toward the end of a stretch of time. To say one thing happens before another, use Before: ansa na.
