There is another kind of composition more frequent in our language than, perhaps, in any other, from which arises to foreigners the greatest difficulty. We modify the signification of many verbs by a particle subjoined; as to _come off_, to escape by a fetch; to _fall on_, to attack; to _fall off_, to apostatize; to _break off_, to stop abruptly; to _bear out_, to justify; to _fall in_, to comply; to _give over_, to cease; to _set off_, to embellish; to _set in_, to begin a continual tenour; to _set out_, to begin a course or journey; to _take off_, to copy; with innumerable expressions of the same kind, of which some appear wildly irregular, being so far distant from the sense of the simple words, that no sagacity will be able to trace the steps by which they arrived at the present use. These I have noted with great care; and though I cannot flatter myself that the collection is complete, I believe I have so far assisted the students of our language, that this kind of phraseology will be no longer insuperable; and the combinations of verbs and particles, by chance omitted, will be easily explained by comparison with those that may be found.
Many words yet stand supported only by the name of Bailey, Ainsworth, Philips, or the contracted Dict, for _Dictionaries_ subjoined; of these I am not always certain, that they are read in any book but the works of lexicographers. Of such I have omitted many, because I had never read them; and many I have inserted, because they may, perhaps, exist, though they have escaped my notice: they are, however, to be yet considered as resting only upon the credit of former dictionaries. Others, which I considered as useful, or know to be proper, though I could not at present support them by authorities, I have suffered to stand upon my own attestation, claiming the same privilege with my predecessors, of being sometimes credited without proof.
The words, thus selected and disposed, are grammatically considered; they are referred to the different parts of speech; traced, when they are irregularly inflected, through their various terminations; and illustrated by observations, not, indeed, of great or striking importance, separately considered, but necessary to the elucidation of our language, and hitherto neglected or forgotten by English grammarians.
