I need HELP!!!!! i dont know the difference between them

highlight in yellow the meaningless words or stale phrases used by Orwell in these paragraphs. highlight in blue the concrete imagines he uses to describe writing.

As I have tried to show, modern writing at its worst does not consist in picking out words for the sake of their meaning and inventing images in order to make the meaning clearer. It consists in gumming together long strips of words which have already been set in order by someone else and making the results presentable by sheer humbug. The attraction of this way of writing is that it is easy. It is easier—even quicker, once you have the habit—to say In my opinion it is not an unjustifiable assumption that than to say I think. If you use ready-made phrases, you not only don’t have to hunt about for the words; you also don’t have to bother with the rhythms of your sentences since these phrases are generally so arranged as to be more or less euphonious. When you are composing in a hurry—when you are dictating to a stenographer, for instance, or making a public speech—it is natural to fall into a pretentious, Latinized style. Tags like a consideration which we should do well to bear in mind or a conclusion to which all of us would readily assent will save many a sentence from coming down with a bump. By using stale metaphors, similes, and idioms, you save much mental effort, at the cost of leaving your meaning vague, not only for your reader but for yourself. This is the significance of mixed metaphors. The sole aim of a metaphor is to call up a visual image. When these images clash—as in The Fascist octopus has sung its swan song, the jackboot is thrown into the melting pot—it can be taken as certain that the writer is not seeing a mental image of the objects he is naming; in other words, he is not really thinking. Look again at the examples I gave at the beginning of this essay. Professor Laski (1) uses five negatives in fifty three words. One of these is superfluous, making nonsense of the whole passage, and in addition, there is the slip—alien for akin—making further nonsense, and several avoidable pieces of clumsiness which increase the general vagueness. Professor Hogben (2) plays ducks and drakes with a battery which is able to write prescriptions, and, while disapproving of the everyday phrase put up with, is unwilling to look egregious up in the dictionary and see what it means; (3), if one takes an uncharitable attitude towards it, is simply meaningless: probably one could work out its intended meaning by reading the whole of the article in which it occurs. In (4), the writer knows more or less what he wants to say, but an accumulation of stale phrases chokes him like tea leaves blocking a sink. In (5), words and meaning have almost parted company. People who write in this manner usually have a general emotional meaning—they dislike one thing and want to express solidarity with another—but they are not interested in the detail of what they are saying. A scrupulous writer, in every sentence that he writes, will ask himself at least four questions, thus:

1. What am I trying to say?
2. What words will express it?
3. What image or idiom will make it clearer?
4. Is this image fresh enough to have an effect? And he will probably ask himself two more:

• Could I put it more shortly?
• Have I said anything that is avoidably ugly?

But you are not obliged to go to all this trouble. You can shirk it by simply throwing your mind open and letting the ready-made phrases come crowding in. The will construct your sentences for you—even think your thoughts for you, to a certain extent—and at need, they will perform the important service of partially concealing your meaning even from yourself. It is at this point that the special connection between politics and the debasement of language becomes clear.
