Usage Notescourse class
There is more to writing and speaking English than knowing what the separate words mean and how they are spelled and pronounced. Words must be put together correctly to make proper sentences, and the words that are used must be suitable to the time and place at which they are used.
You have already seen how this dictionary labels certain main entries and definitions informal or slang. These labels warn you against putting something unsuitable into a dignified, formal composition or speech. When such a label is not enough to explain exactly how a word can be used, a * note will tell you what you need to know. For example, is it ever correct to use ain't? Here is the dictionary's explanation:курсы немецкого языка вена
ain't A contraction of: Am not: I ain't going. Ain't is also used for are not, is not, has not, and have not. + Ain't is not considered acceptable English today, although speakers and writers sometimes use it for humorous effect.
This note explains why you may see ain't in books when the author is trying to be funny or when a character is supposed to be speaking nonstandard English. But most people, including your teacher, usually classify a person who uses ain't seriously as untaught and handicapped by poor background. When you know the difference, it is wise to use acceptable English only.german teacher vienna
Other * notes help you with still more complicated problems of correct usage. To see how this works, look first at the main entry printed here:
as-tro-nau-tics n. The science and art of flight in space.
Now imagine that you have looked up the cross-reference, and read the main entry for the suffix -ics:
-ics A suffix meaning: 1 An art, science, or field of study, as in mathematics. 2 Methods, systems, or activities, as in acrobatics, athletics. •» Nouns ending in -ics that refer to arts, sciences, or fields of activity were originally plural, meaning things relating to a field. Later they came to mean all such things relating to a field, taken as a single collection, and they became singular: Politics is exciting; Physics is his favorite subject. Such words seldom take a, an, or the. Nouns in -ics that refer to specific details, qualities, or methods within a field are plural and often take articles: The acoustics in this hall are bad; These statistics are from the last census.
The entry for astronautics gives you the basic dictionary information: spelling, pronunciation, and meaning. But to get the most possible information, you follow up the cross-reference and learn about the correct use of words ending in -ics. Do you see the two points this » note is making? First, it tells when to use a singular verb and when to use a plural verb. And, second, you learn that ordinarily you do not use a, an, or the with these words when the singular verb is the correct one.
Every time a word ending in -ics appears in your dictionary, it is followed by the cross-reference "See -ics." Usage notes like this give you another reason to look up cross-references whenever you find them.
