Word Forms
Many items give one root word and ask for the correct form. The grammar of the sentence signals whether a noun, verb, adjective, or adverb belongs in the blank. This chapter reviews how position determines part of speech.
Nouns After Quantity Words
After words like 'several' or 'many', a plural noun is expected: 'several improvements'. Recognizing the noun form of a root (improve to improvements) keeps the sentence correct.
Adverbs and Adjectives
Adverbs describe verbs ('handled it professionally'), while adjectives follow linking verbs and describe nouns ('the instructions were clear'). The word being described tells you the form.
Base Verbs After 'To'
The infinitive marker 'to' takes a base verb: 'decided to postpone'. Choosing the noun form ('postponement') after 'to' is a frequent error.
