להתפשט, lehitpashet: As discussed today in class, this word means "to become common;" ie. for information to spread and thus practice to become common. We'll call that the high interpretation.
In modern Hebrew it also means "to get undressed." From the root of the word simple, the reflexive verb means "to become simple." Or in other words, to get back to basics.
הייתי פה, hayiti po: Literally means "I was here." Colloquially it means, "I'm outta here."
סובלנות, sovlanut: Hebrew has one word both for suffering and tolerance. Discuss amongst yourselves.
