Well is sometimes used elliptically for it is well, as an expression of satisfaction with what has been said or done, and sometimes it expresses concession, or is merely expletive; as, well, the work is done; well, let us go; well, well, be it so.

Well, like above, ill, and so, is used before many participial adjectives in its usual adverbial senses, and subject to the same custom with regard to the use of the hyphen (see the Note under Ill, adv.); as, a well-affected supporter; he was well affected toward the project; a well-trained speaker; he was well trained in speaking; well-educated, or well educated; well-dressed, or well dressed; well-appearing; well-behaved; well-controlled; well-designed; well-directed; well-formed; well-meant; well-minded; well-ordered; well-performed; well-pleased; well-pleasing; well-seasoned; well-steered; well-tasted; well-told, etc. Such compound epithets usually have an obvious meaning, and since they may be formed at will, only a few of this class are given in the Vocabulary.
