【Amateur】 , 【Dilettante】 , 【Dabbler】 and 【Tyro】 denote a person who follows a pursuit without attaining proficiency or a professional status.
【Amateur】 may denote one who has a taste or liking for something rather than an expert knowledge of it; in this sense it is distinguished from connoisseur.
an 【amateur】 of cameos
affected the pose of the gentleman 【amateur】 of the arts —F. H. Ellis
【Amateur】 is also applied to a person whose participation in an activity requiring skill is due to a personal rather than a professional interest. It usually but not invariably implies a lack of mastery. This latter implication is not often found in sports, where a technical distinction between an 【amateur】 (one who competes without remuneration) and a professional (one who competes for reward) prevails. In other use the word is opposed to expert and adept, as well as professional. Sometimes it suggests lack of experience or apprenticeship.
every artist was first an 【amateur】 —Emerson
Sometimes it connotes indulgence in a particular pursuit as a pastime or as an avocation.
how could an 【amateur】 venture out and make an exhibition of himself after such splendid rowing! —Jefferies
Very often, especially in contrast to expert or adept, it connotes superficiality, bungling, or indifference to professional standards.
it is beginning to be hinted that we are a nation of amateurs —Rosebery
the third earl of Shaftesbury . . . illustrated this unsystematic method of thinking. He was an 【amateur】 , an aristocratic 【amateur】 , careless of consistency —Ellis
【Dilettante】 is applied to an 【amateur】 (in the older underogatory sense of that word) in the fine arts (see AESTHETE). It stresses enjoyment rather than effort, a frittering rather than a concentration of one's energies, and, sometimes, the point of view of the aesthete.
the 【dilettante】 lives an easy, butterfly life, knowing nothing o f . . . toil and labor —Osier
we continue to respect the erudite mind, and to decry the appreciative spirit as amateurish and 【dilettante】 —Benson
【Dabbler】 implies a lack of serious purpose, but it suggests desultory habits of work and lack of persistence.
your dabblers in metaphysics are the most dangerous creatures breathing —Tucker
the certainty of touch which marks the difference between an artist and the 【dabbler】 . . . can come only after patient study —Wendell
【Tyro】 does not necessarily imply youth but does suggest comparable inexperience or audacity with resulting incompetence or crudeness.
it may be fancy on the part of a 【tyro】 in music to suggest that a change from poetry to prose occurs when Beethoven introduces in the last movement of the Choral Symphony . . . a subject in words —Alexander
"a noble theme!" the 【tyro】 cried, and straightway scribbled off a sonnet. "A noble theme," the poet sighed, "I am not fit to write upon it" —Wells
