With singular nouns, determiners are necessary. Use an indefinite article to talk generically about a singular noun (a or an). Don't use a determiner when referring to a plural word generally. Use a definite article, demonstrative pronoun, possessive pronoun, or quantifier to talk precisely about a singular word.
