Thus I know not whether _ardor_ is used for _material heat_, or whether _flagrant_, in English, ever signifies the same with _burning_; yet such are the primitive ideas of these words, which are therefore set first, though without examples, that the figurative senses may be commodiously deduced.
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 he 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 word commits errors, 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.
