Lesson 26 introduces terminology related to time prepositions and expansion of time terminology.
Time preposition:
"Beh" (equivalent of "on") always used before specific time.
Specific time is with reference to the time of day.
When a time of event is referred as before or after another event, the preposition "Beh" is not used (rather it is one of the prepositions before or after.
Also lesson 26 introduces another way to relate to entire population.
In lesson 15 the word "Col" was introduced as "All", and in the future it will be introduced as "Each"/"Every". In lesson 26 the word "Col" is introduced equivalently to "the whole" or "the entire".
