(3) Although rise/raise and reise may be said to be false friends, they also have overlapping meanings, acting as "true friends". The different contexts in which the words occur must be seen as the main reason for this split. In contexts such as those under (1), the English and Norwegian words differ in meaning, while in contexts such as those under (2), they have similar meanings. Words are coloured by their surroundings, and in this case the apparently false friends can in some contexts take on similar meanings. Some words, however, are more stable false friends, e.g. "accurate" vs. "akkurat", "pig" vs. "pigg".
(4) Rise and reise may take on the following meaning when they are true friends: "get to one's feet" ("reise seg").
Raise and reise may take on the following meaning when they are true friends: "to put forward for consideration" ("stille") or "erect" ("sette opp"). (Other meanings can also be found, particularly in the case of raise vs. reise.)
