Such is the exuberance of signification which many words have obtained, that it was scarcely possible to collect all their senses; sometimes the meaning of derivatives must be sought in the mother term, and sometimes deficient explanations of the primitive may be supplied in the train of derivation.  In any case of doubt or difficulty, it will be always proper to examine all the words of the same race; for some words are slightly passed over to avoid repetition; some admitted easier and clearer explanation than others; and all will be better understood, as they are considered in greater variety of structures and relations.

All the interpretations of words are not written with the same skill, or the same happiness:  things, equally easy in themselves, are not all equally easy to any single mind.  Every writer of a long work commits errours, where there appears neither ambiguity to mislead, nor obscurity to confound him:  and, in a search like this, many felicities of expression will be casually overlooked, many convenient parallels will be forgotten, and many particulars will admit improvement from a mind utterly unequal to the whole performance.

But many seeming faults are to be imputed rather to the nature of the undertaking, than the negligence of the performer.  Thus some explanations are unavoidably reciprocal or circular, as hind, the female of the stag; stag, the male of the hind:  sometimes easier words are changed into harder, as burial into sepulture, or interment, drier into desiccative, dryness into siccity or aridity, fit into paroxysm; for the easiest word, whatever it be, can never be translated into one more easy.  But easiness and difficulty are merely relative; and, if the present prevalence of our language should invite foreigners to this Dictionary, many will be assisted by those words, which now seem only to increase or produce obscurity.  For this reason I have endeavoured frequently to join a Teutonick and Roman interpretation, as to cheer, to gladden or exhilarate, that every learner of English may be assisted by his own tongue.

The solution of all difficulties, and the supply of all defects, must be sought in the examples, subjoined to the various senses of each word, and ranged according to the time of their authors.

When I first collected these authorities, I was desirous that every quotation should be useful to some other end than the illustration of a word; I, therefore, extracted from philosophers principles of science; from historians remarkable facts; from chymists complete processes; from divines striking exhortations; and from poets beautiful descriptions.  Such is design, while it is yet at a distance from execution.  When the time called upon me to range this accumulation of elegance and wisdom into an alphabetical series, I soon discovered that the bulk of my volumes would
