Roger Woodham replies:Rise, arise and raise

Rise - rose - risen

Generally, if something rises it moves upwards. If you rise, this is a rather formal way of saying that you get of out bed, get up or stand up:

When the sun and the moon rise, they appear in the sky. If the water in a river rises, it becomes higher. If the wind rises, it blows more strongly:

Arise - arose - arisen

Arise is mainly used in a more abstract way. If a situation or problem or something arises, it comes into being and people become aware of it:

We can also use arise to mean to get up, get out of bed or stand up, but it is even more formal than rise in this sense. Note that when a knighthood is bestowed in Britain, the monarch touches the recipient's shoulders with a sword and then says, e.g.

meaning that he, William, may now (a)rise from his kneeling position as a knight of the realm.

Raise - raised - raised

If you raise something, you move it to a higher position. If you raise your voice, you speak more loudly. If you raise the standard of something, you improve it:

Note that raise is a regular verb, whereas rise is irregular. Note also that raise is a transitive verb, in other words, it must always be used with a direct object. You always raise something. Rise, on the other hand, is an intransitive verb: it does not involve anything or anyone other than the subject.

Note the following idiomatic expressions with raise:

to raise the alarm = warn people of danger

not to raise or lift a finger = do nothing to help

to raise a smile or a laugh = say something which makes people smile or laugh

to raise the roof = make a building reverberate with loud singing, shouting, clapping etc
