Word Forms
Many items give a 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 Possessives
A noun follows a possessive: 'his determination'. Learning the noun form of a root (determine to determination) prevents choosing the wrong part of speech.
-ing and -ed Adjectives
'-ing' adjectives describe the source of a feeling ('a moving film'), while '-ed' adjectives describe how someone feels ('I felt moved'). Choosing the right one depends on what is being described.
Base Verbs After 'To'
The infinitive marker 'to' takes a base verb: 'need to change our plans'. Choosing an adjective form ('changeable') after 'to' is a common error.
