Century Dictionary and Cyclopedia

1. n. A deed; especially, a noteworthy or extraordinary act or performance; an exploit: as, feats of arms; feats of horsemanship or of dexterity.
2. n. Synonyms Deed, Feat, Exploit, Achievement. These words are arranged in the order of strength; deed, however, may have a much more elevated character than feat, and even surpass exploit. A deed may, on the other hand, be base or ignoble. It is, therefore, often accompanied by an adjective of quality. A feat is generally an act of remarkable skill or strength: as, the feats of a juggler, a ventriloquist, an athlete. An exploit is especially an act of boldness or bravery, with various degrees of mental power in working it out. An achievement is the result of large ability in planning, and diligence and boldness in executing. Feat, exploit, and achievement differ from act, action, and deed in that the first three always, and the last three only sometimes, represent something great.
3. To form; fashion; set an example to.
4. Neat; skilful; ingenious; deft; clever.
5. Large: as, a pretty feat parcel (a rather large quantity).
6. To make neat.
